[0012] This invention discloses an application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass material properties. The technical problem it addresses is different from the closest existing technology, and the disclosed technical features are also different.

[0013] Background technology [I]. And various prior background technologies [2], and all prior technologies have not been fully revealed:

[0014] This invention relates to the application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass properties. The chemical composition of the glass material, calculated by weight percentage, includes: 0-20% boron oxide, 4-20% magnesium oxide, 13-45% aluminum oxide, 0-6% zirconium, and 0-20% sodium oxide or potassium oxide. Among these, the content of silicon oxide is 0.8 to 6 times that of calcium oxide, and the content of calcium oxide is 0.3 to 2.5 times that of magnesium oxide. The crystallization temperature in the gradient furnace crystallization experiment is between 1100-830°C, which is significantly lower than the forming viscosity temperature at which the glass melt enters the (2.8)log P logarithm. The viscosity range of the glass melt entering the forming operation zone is (4.25-5.57)log P, corresponding to a temperature of 850℃-1240℃ or less than 850℃-1240℃; the crystallization temperature of the gradient furnace crystallization experiment is between 1100-830℃, which is significantly lower than the forming viscosity temperature of the glass melt entering the (2.8)log P logarithm.

[0015] The glass material can form a three-dimensional network structure with atomic-level ultra-precision manufacturing characteristics, which can produce new material properties with fracture toughness of 0.8-1.6 (MPa*m1 / 2) and elastic modulus of 80-200 Gpa.

[0016] Background Art [1]: Sodium-calcium glass and some prior art. Background Art [2]: Authorization Announcement No. CN103232160B Authorization Announcement Date 2018.07.24 Invention Title - A flat glass with a low coefficient of thermal expansion and its manufacturing process, etc. And all prior art, none of which fully discloses:

[0017] The present invention has the following manufacturing characteristics with atomic-level precision network structure: 1. No one has disclosed the crystallization temperature of the alkali-free glass product with 13-45% alumina in the present invention. The crystallization temperature of the gradient furnace crystallization experiment is between 1100-830℃, which is significantly lower than the material property of the glass melt entering the forming viscosity temperature of (2.8)log P logarithm. Therefore, the present invention will not produce new material properties of crystallization before the glass melt enters the tin bath in processes such as float glass.

[0018] 2. No one has disclosed the test of the present invention using an atmosphere furnace with precise temperature control, or the test of a glass high-temperature viscosity tester under the condition that the platinum rotor is stopped. In the process stage where the glass melt enters the forming viscosity temperature of (2.8)log P logarithmic value, and then enters the forming operation zone temperature of the glass melt, the viscosity range of which is (4.25-5.57)log P viscosity temperature process stage, the glass melt does not produce special new glass properties characteristic data within a time of not less than 60 minutes.

[0019] Only by producing the alkali-free glass of the present invention with an alumina content of 13-26 or 26-36-45%, can the viscosity-temperature logarithm (1.5)log P be approximately 1400-1540℃ during the melting stage. The glass viscosity-temperature logarithm (2.0)log P is approximately 1440-1340℃. The very low glass viscosity-temperature logarithm of the present invention enables the product to be mass-produced. This overcomes and solves the historical technical problem that has plagued the production of high-alumina alkali-free glass products—the short product material properties, making it prone to crystallization and hindering normal production—a problem that people have long sought to solve but have not been able to resolve.

[0020] Because the traditional glass melting and degassing process involves equipment containing approximately 12% alumina and over 10% potassium and sodium, the so-called high-alumina glass (alkali-containing) has a viscosity-temperature logarithm of (1.5)log P of approximately 1700℃ during the melting stage. The viscosity-temperature logarithm of (2.0)log P for degassing is approximately 1600℃.

[0021] No one has disclosed the alkali-free glass products of the present invention with 13-45% alumina. The crystallization temperature of the gradient furnace crystallization experiment is between 1100-830℃, which is significantly lower than the material properties of the glass melt entering the forming viscosity temperature of (2.8)log P logarithm. Therefore, the present invention will not produce new material properties of crystallization before the glass melt enters the tin bath in processes such as float glass.

[0022] No one has disclosed any new glass property characteristic data of the present invention, which is that the glass melt does not crystallize within a process stage region from the forming viscosity temperature of (2.8)log P to the forming operation temperature of the glass melt, where the viscosity range is (4.25-5.57)log P, and the glass melt passes through a process stage of not less than 60 minutes.

[0023] Therefore, people dare not produce alkali-free glass products with 13-45% alumina on the production line.

[0024] Although the present invention has some negative effects compared to the prior art [1] and [2] in some aspects, it has significant positive technical effects in other aspects.

[0025] The technical features disclosed in this invention are also different from the background technology [1] and [2] and all prior art.

[0026] The technical features of this invention are also different from those of the background technologies [1] and [2]. The application of a glass with atomically precise network structure, low forming zone temperature and specific glass material properties—a newly discovered material property—solves a technical problem in glass product applications that is also different from those of the background technologies [1] and [2].

[0027] The glass products containing 13-26 or 26-36-45% alumina in the above-mentioned technical solutions of the present invention have been newly discovered. A new type of glass with atomically precise network structure manufacturing characteristics, low forming zone temperature and specific glass material properties has been discovered. Utilizing the new properties of the glass network structure, unexpected new material properties can be generated with a fracture toughness of 0.8-1.6 (MPa*m1 / 2) and an elastic modulus of 80-200 Gpa.

[0028] In the application of glass, a fragile material, this invention can exhibit higher fracture toughness and strength properties than existing products. In terms of quantifiable major technical characteristics (for example, the elastic modulus of ordinary glass products is only 40-50 GPa, and the fracture toughness is only 0.3-0.4 (MPa*m1 / 2), the technical effect produced by the present invention is much better. The technical problems solved in the application of glass products are also different from those in the background technologies [1] and [2].

[0029] (1) Most importantly, the application of the characteristic glass of this invention, which features an atomically precise network structure, low forming zone temperature, and specific glass properties:

[0030] 1. This invention discloses a material property previously undisclosed: for alkali-free glass products with 13-45% alumina, the crystallization temperature in a gradient furnace crystallization experiment is between 1100-830°C, which is significantly lower than the forming viscosity temperature of the molten glass entering the (2.8)log P logarithm. Therefore, this invention will not produce a new material property of crystallization before the molten glass enters the tin bath in processes such as float glass.

[0031] 2. This invention discloses a novel, previously undisclosed quantitative testing method for obtaining data on the length and width of glass materials, revealing new physicochemical properties of alkali-free glass products with 13-26 or 26-36-45% alumina content. The alkali-free glass of this invention with 13-26 or 26-36-45% alumina content exhibits a viscosity-temperature logarithm (1.5)log P of approximately 1400-1540°C during the melting stage. The glass viscosity-temperature logarithm (2.0)log P, after bubble removal, is approximately 1440-1340°C. This invention's very low glass viscosity-temperature logarithm material properties enable mass production.

[0032] This led to a historic problem that could be solved with high-alumina alkali-free glass products, but the production technology that could not be applied resulted in unexpected technological effects.

[0033] (2) Because it can produce alkali-free glass with an alumina content of 13-26 or 26-36-45% according to the present invention, the viscosity temperature logarithm (1.5)log P during the melting stage is about 1400-1540°C. The glass viscosity temperature logarithm (2.0)log P after degassing is about 1440-1340°C. The material properties of the present invention with very low glass viscosity temperature logarithm enable mass production.

[0034] Furthermore, in the traditional glass melting and bubble removal process, the melting stage of so-called high-alumina glass (alkali-containing glass), which contains approximately 12% alumina and more than 10% potassium and sodium, has a viscosity-temperature logarithm of (1.5)log P of approximately 1700℃. The viscosity-temperature logarithm of (2.0)log P for bubble removal is approximately 1600℃.

[0035] (3) Therefore, the present invention can also utilize the newly discovered and verifiable new properties of the material of the present invention that do not produce crystallization, resulting in unexpected technical effects:

[0036] This invention can change and eliminate the need for traditional high-alumina glass (containing alkali) in terms of production process equipment and thermal raw materials. Traditional high-alumina glass melting and bubble removal processes involve excessively high viscosity and temperatures, necessitating the use of natural gas as fuel. This invention allows for the use of electric melting furnaces for glass with 13-26% or 26-36-45% alumina content. This results in unexpected large-scale energy savings in the glass industry.

[0037] As professionals know, the thermal energy utilization rate of a fully electric furnace system is 80%, while that of a natural gas furnace system is only 40%.

[0038] Furthermore, as professionals know, in glass production, increasing the temperature from 1400 degrees Celsius to 1500 degrees Celsius generally increases energy consumption by about 20%-30%. This is because in this temperature range, the viscosity of the molten glass decreases further, requiring more heat to maintain the temperature and ensure the uniformity of the glass. Simultaneously, heat losses, such as those from the furnace, also increase significantly. From 1500 degrees Celsius to 1600 degrees Celsius, energy consumption typically increases by 30%-40%. As the temperature continues to rise, the heat demand of the molten glass increases exponentially. Moreover, at high temperatures, heat losses from the furnace's refractory materials and thermal radiation increase dramatically. Additionally, to ensure glass quality, the precision required for temperature control is higher, which also leads to a substantial increase in energy consumption.

[0039] The process was changed to an electric melting furnace. This resulted in unexpected technological benefits, including large-scale energy savings in the glass industry.

[0040] A forming process for a glass material with low crystallization strength, short material properties, high elastic modulus, high fracture toughness, and low forming zone temperature includes, but is not limited to, float forming, calendering, casting, overflow drawing, slurry drawing, and tube drawing processes.

[0041] (4) Application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass properties – a new discovery:

[0042] This invention discloses a previously undisclosed alkali-free glass product with 13-45% alumina. The crystallization temperature in the gradient furnace crystallization experiment is between 1100-830°C, which is significantly lower than the forming viscosity temperature of the glass melt entering the (2.8)log P logarithm. Therefore, crystallization will not occur before the glass melt enters the tin bath in processes such as float glass.

[0043] This invention discloses a novel, previously undisclosed, quantitative testing method for obtaining data on the length and intensity of glass properties. This method reveals new physicochemical properties of alkali-free glass products with 13-26 or 26-36-45% alumina content. Further explanation is provided regarding the quantitative testing method for these glass properties, including whether they affect crystal formation during production.

[0044] Because in the float glass process, the glass ribbon enters the tin bath, and during the leveling and polishing stages, the viscosity logarithm of this area is (2.7-3.2) log P for about 6 minutes. Then, the glass ribbon is pulled by about 20 pairs of edge-pulling machines to a thickness of 0.3-0.5 mm, which is approximately 6 minutes, until the viscosity logarithm of this area is (4.2-5.75) log P. At this point, the glass ribbon is nearly hardened and will not crystallize, and it will leave the tin bath, which takes about 6 minutes. The total time is approximately 18 minutes.

[0045] This invention employs a quantitative testing method, focusing not on the glass crystallization point temperature, but more importantly on the low crystallization strength and short material properties, especially for alkali-free glass products with 13-26 or 26-36-45% alumina content. A quantifiable testing method is used to measure the time from when the molten glass enters the forming process to when it hardens and no longer crystallizes, obtaining data on the length of the glass material properties and whether this affects the formation of crystals in the glass product during production.

[0046] Example 2. The present invention employs a quantitative testing method, Example 1:

[0047] We used a glass experimental atmosphere furnace with precise temperature control. The glass raw material of this invention was placed in a dry crucible for testing, melted, and then cooled after reaching 1400 degrees Celsius. Next, the temperature was controlled to maintain the glass at a viscosity logarithm of (2.7-3.2) log P, then at (4.2-5.75) log P, and finally at (5.75-10) log P, for a total time exceeding 60 minutes before removal. The requirement was that the melted glass in the experimental dry crucible should not exhibit crystallization after removal. This means that even with a time exceeding three times the approximately 18 minutes required for the glass to enter the tin bath and harden during glass production (60 minutes), crystallization should not occur.

[0048] For example, regarding the testing we use with a high-temperature glass viscosity tester: Why does the rotation of the platinum rotor need to be stopped when the molten glass enters the bubble-removing viscosity temperature stage (2.0)log P logarithmic value during the high-temperature glass viscosity tester test?

[0049] When making alkali-free glass products with 13-26 or 26-36-45% alumina according to the present invention, and using a high-temperature viscometer to test the viscosity temperature of the glass, because the glass viscosity is low in the high-temperature zone, the platinum rotor has to rotate once every 2-3 minutes in a very small dry crucible in glass melt that is hundreds of thousands of times less than the production conditions, which will generate a high proportion of friction on the glass melt.

[0050] According to the principles of crystallization conditions in glass technology, a high proportion of friction caused by the continuous rotation of molten glass makes it easier for alumina in the molten glass to transform into seed crystals, increasing the intensity of glass crystallization and causing problems such as grain growth and glass devitrification.

[0051] In the stage of viscosity logarithm (1.5)-(3.0-5.5)log P, if the high temperature viscometer rotates at 2 degrees per minute for about 3-4 hours during a long process, it is easy to increase the glass crystallization intensity. Alumina is easy to transform into crystal seeds, which increases the glass crystallization intensity and causes grain growth and glass devitrification. This is different from the normal glass production process.

[0052] In the float glass process, during the glass ribbon leveling and polishing stages: the viscosity logarithm of this zone is (2.7-3.2) log P. The glass ribbon enters the tin bath and is pulled out after cooling – the viscosity logarithm of this zone is (5.75-7) log P. This takes approximately 12-15 minutes. Unlike high-temperature viscometers, which, due to the low viscosity of glass in the high-temperature zone, require the platinum rotor to rotate once every 2-3 minutes in a small volume of molten glass in a dry crucible, resulting in high friction against the molten glass, the platinum rotor cannot rotate for 3-4 hours in a small volume of molten glass. This friction easily increases the glass crystallization intensity, and alumina easily transforms into seed crystals, further increasing the glass crystallization intensity and leading to grain growth and glass devitrification.

[0053] Therefore, this invention discloses an application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass material properties: it reveals a previously undisclosed material property of alkali-free glass products with 13-45% alumina, whose crystallization temperature in a gradient furnace crystallization experiment is between 1100-830℃, significantly lower than the forming viscosity temperature of the molten glass entering the (2.8)log P logarithm. Therefore, it does not produce crystallization before the molten glass enters the tin bath in processes such as float glass. This reveals a new discovery previously undisclosed (the glass product with 13-26 or 26-36-45% alumina in the above technical solution), which can be tested using a quantitative testing method under certain conditions on a high-temperature glass viscosity tester: 1. The forming viscosity temperature at which the glass melt enters the forming operation zone, where the viscosity range is (4.25-5.57) log P; 3. The viscosity temperature at which the glass melt enters the forming operation zone, where the viscosity range is (5.75-8) log P; P, the glass ribbon is nearing the viscosity and temperature stage of hardening and will not crystallize; after a time of not less than 60 minutes, the glass does not crystallize. When the glass melt is kept at a temperature 3 times longer than normal production conditions, or 6-9 times longer (120-180 minutes), crystallization still does not occur. This proves that the high-tech product of this invention, alkali-free glass with low crystallization strength and short material properties (13-26 or 26-36-45% alumina), can solve the historical technical problem that has plagued the production of products with short material properties, making them prone to crystallization and unable to be produced normally—a problem that people have long wanted to solve but have not been able to solve.

[0054] (2)

[0055] The industrial revolution of the three-dimensional network structure of glass products manufactured at the atomic level:

[0056] Our innovation in glass materials stems from fundamental technological breakthroughs that transform the three-dimensional network structure of glass products manufactured at the atomic level, rather than simply introducing new glass materials. It involves innovative breakthroughs in hundreds of different sub-categories of glass product components and their varying physicochemical properties.

[0057] [I] In the three-dimensional network structure of atoms in glass product technology, alumina is a network intermediate oxide. This is due to the relationship between network generation and network externalities.

[0058] There are only two types of network structures in glass product technology: The first is a network structure where aluminum and silicon atoms are linked together by sharing one or two oxygen atoms; this is the strongest network structure in glass materials. The second is a network structure where silicon atoms are linked together by sharing one oxygen atom; this type is less strong and easily disrupted by the presence of alkaline components such as potassium or sodium in the glass. This significantly reduces the glass's properties, including fracture toughness, elastic modulus, microhardness, and abrasion resistance.

[0059] When the alumina content is less than 2%, the aluminum atoms in the flat glass are almost entirely in a 4-coordinated configuration, forming a structure where each aluminum atom is surrounded by four oxygen atoms.

[0060] When the alumina content exceeds 10%, aluminum atoms in flat glass will exist in 4-, 6-, or 8-coordinated forms, forming a structure with 4, 6, or 8 oxygen atoms surrounding the aluminum atom.

[0061] Alkali-free glass with 13-26 or 26-36-45% alumina content, which demonstrates the novel properties of this invention—low forming zone temperature and special glass characteristics—is produced.

[0062] Although the present invention has some negative effects compared to the prior art [1] and [2] in some aspects, it has significant positive technical effects in other aspects.

[0063] The technical features disclosed in this invention are also different from the background technology [1] and [2] and all prior art.

[0122] Using a temperature-controlled atmosphere furnace or a glass high-temperature viscosity tester with the platinum rotor stopped, the glass melt enters the forming viscosity temperature range of (2.8)log P and then enters the forming operation zone. The viscosity temperature range of this zone is (4.25-5.57)log P. If the glass melt passes through this process zone for at least 60 minutes, the glass melt will not exhibit any special glass material characteristics such as crystallization.

[0123] The application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass properties according to claim 1 is characterized by comprising: a boron oxide content of 1-15%, a sodium oxide or potassium oxide content of 0-2% or 0-5%, and a viscosity temperature logarithm of (1.5)log P of approximately 1400-1540℃ during the glass melting stage; a glass viscosity temperature logarithm of (2.0)log P of approximately 1440-1340℃ for bubble removal; and a crystallization temperature in the gradient furnace crystallization experiment between 1220-830℃. This material property is significantly lower than the forming viscosity temperature logarithm of (2.8)log P, therefore crystallization will not occur before the glass melt enters the tin bath in processes such as float glass.

[0124] This invention discloses—a previously undisclosed test using an atmosphere furnace with precisely controlled temperature, or a glass high-temperature viscosity tester with the platinum rotor stopped—that, in the process stage from the glass melt entering the forming viscosity temperature range of (2.8) log P to the forming operation temperature range of (4.25-5.57) log P, the glass melt does not exhibit special glass material characteristics of crystallization within a time period of not less than 60 minutes.

[0125] Includes: boron oxide content of 1-15%, sodium oxide or potassium oxide content of 0-2% or 0-5%. During the glass melting stage, the viscosity-temperature logarithm (1.5)log P is approximately 1400-1540℃.

[0128] In the examples, the sodium oxide content may be 0-0.5%, 2-3.5%, 3-5%, 5-10%, or 5-18%.

[0129] In the embodiments, the glass structure of the present invention, characterized by an atomic-level network structure, contains 0.3-6% zirconium. This zirconium undergoes a phase transition at high temperatures, creating stress within the three-dimensional space of the glass, thus increasing the elastic modulus of the glass. Furthermore, the 0.3-4% zirconium content contributes to high thermal shock resistance, preventing cracking or breakage during rapid temperature changes. Finally, the 1-6% zirconium content, coupled with its diameter exceeding the wavelength of visible light, contributes to the glass's opacity, allowing for various product applications.

[0130] In this embodiment, the application of a glass product with an atomically precise network structure includes, but is not limited to, omitting natural gas as the heating material for glass melting and using all-electric melting heating as the heating material. This can produce unexpected technical effects such as large-scale energy savings and significant cost reduction.

[0131] Example 5:

[0132] This invention relates to a glass wafer substrate with atomically precise network structure manufacturing characteristics, low forming zone temperature, and exceptionally high elastic modulus and fracture toughness, as well as the application of glass substrate chips and packaging materials with high elastic modulus and fracture toughness. The technical problems it addresses differ from the closest existing technology, and the disclosed technical features are also different.

[0133] Application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass properties. The chemical composition of this glass material, calculated by weight percentage, includes: 0-20% boron oxide, 4-20% magnesium oxide, 13-45% aluminum oxide, 0-6% zirconium, and 0-20% sodium oxide or potassium oxide. The content of silicon oxide is 0.8 to 6 times that of calcium oxide, and the content of calcium oxide is 0.3 to 2.5 times that of magnesium oxide. The viscosity range of the glass melt entering the forming operation zone is (4.25-5.57) log P, corresponding to a temperature of 850℃-1240℃ or less than 850℃-1240℃.

[0134] The glass material can form a three-dimensional network structure with atomic-level ultra-precision manufacturing characteristics, which can produce new material properties with fracture toughness of 0.8-1.6 (MPa*m1 / 2) and elastic modulus of 80-200 Gpa.

[0135] Includes: boron oxide content of 1-15%, sodium oxide or potassium oxide content of 0-2% or 0-5%. During the glass melting stage, the viscosity-temperature logarithm (1.5)log P is approximately 1400-1540℃. The glass viscosity-temperature logarithm (2.0)log P after degassing is approximately 1440-1340℃.

[0136] The degassing temperature (2.0)log P of the glass viscosity logarithm is approximately 1440-1340℃; the crystallization temperature in the gradient furnace crystallization experiment is between 1220-830℃. This is a material property significantly lower than the forming viscosity temperature (2.8)log P logarithm of the glass melt, so crystallization will not occur before the glass melt enters the tin bath in processes such as float glass.

[0137] In the embodiments, the cerium oxide content may be 0.5%, 0.5-1%, 1-2%, or 2-9%.

[0138] In the embodiments, the glass structure of the present invention, characterized by an atomic-level network structure, contains 0.3-6% zirconium. This zirconium undergoes a phase transition at high temperatures, creating stress within the three-dimensional space of the glass, thus increasing the elastic modulus of the glass. Furthermore, the 0.3-4% zirconium content contributes to high thermal shock resistance, preventing cracking or breakage during rapid temperature changes. Finally, the 1-6% zirconium content, coupled with its diameter exceeding the wavelength of visible light, contributes to the glass's opacity, allowing for various product applications.

[0139] In this embodiment, the application of a glass product with an atomically precise network structure includes, but is not limited to, omitting natural gas as the heating material for glass melting and using all-electric melting heating as the heating material. This can produce unexpected technical effects such as large-scale energy savings and significant cost reduction.

[0140] The application of a characteristic glass with atomically precise network structure manufacturing features, low forming zone temperature, and specific glass properties as described in claim 1 is characterized by including: glass wafer substrates with high elastic modulus and high fracture toughness, and glass substrate chips and packaging materials with alumina content of 13-18%, 18.1-22%, 22.1-26%, 26.1-31%, 31.1-36%, 36.1-40%, or 40.1-45% alumina content, resulting in unexpected technical effects.

[0141] The first technical effect is that the present invention has a glass structure with atomic-level network structure manufacturing characteristics. When applied to glass wafer substrates, it can eliminate the need for photolithography machines and photoresists. This is actually a significant change in the entire technical route, which will reduce costs, improve efficiency, and make the technical route independent.

[0142] The second technical benefit is that this invention features an atomic-level network structure for manufacturing glass substrates. In applications with glass wafer substrates, the alkali-free glass with an alumina content of 26-36-45% exhibits significantly higher elastic modulus, flexural strength, and fracture toughness than ordinary high-alumina glass. Since drilling over a million holes in a fingernail-sized piece of glass using a femtosecond laser, under the same strength requirements, the glass wafer substrate can be made much thinner. This greatly reduces the processing energy and temperature of the laser equipment, significantly simplifying heat dissipation at high temperatures. This has a substantial benefit in increasing the yield rate of glass wafer substrate production.

[0143] The third technical benefit is that this invention features an atomic-level network structure for manufacturing glass substrates. In applications with glass wafer substrates, the alkali-free glass with an alumina content of 26-36-45% exhibits significantly higher elastic modulus, flexural strength, and fracture toughness than ordinary high-alumina glass. Under the same strength conditions, the glass wafer substrate can be made thinner, helping to overcome the significant temperature differences caused by laser equipment (which can only drill 5000 holes at a time, requiring 200 passes to complete one hole). This overcomes the difficulties of deformation and unevenness caused by these temperature differences, and also reduces the probability and difficulty of microcracks in the glass wafer substrate. This greatly improves the yield rate in glass wafer substrate production.

[0144] The fourth technical effect is that this invention features an atomic-level network structure in its glass structure manufacturing. In applications with glass wafer substrates, the alkali-free glass with an alumina content of 26-36-45% has significantly higher elastic modulus, flexural strength, and fracture toughness than ordinary high-alumina glass. Under the same strength conditions, the material of this invention allows for thinner glass wafer substrates, greatly reducing the diameter of the chipping at the bottom of the holes during laser drilling. This helps overcome the problem of excessive chipping at the bottom of over a million holes, leading to interconnected chipping. This ensures that when using metal-filled processes, complex metal integrated circuits will not be connected in series, preventing unwanted intersections, interconnections, parallel connections, or misalignments. In other words, it greatly reduces the probability of such occurrences, significantly improving the yield rate in glass wafer substrate production.

The glass viscosity-temperature logarithm (2.0)log P after degassing is approximately 1440-1340℃.

[0154] The cover glass material possesses a novel property: it can form a three-dimensional network structure with atomic-level ultra-precision manufacturing characteristics. The fracture toughness of the cover glass network structure glass material is 0.7-1.5 MPa*m. 1 / 2 Its elastic modulus is 75-160 GPa;

[0155] Using a temperature-controlled atmosphere furnace or a high-temperature glass viscosity tester with the platinum rotor stopped, the glass melt enters the forming viscosity temperature range of (2.8)log P and then enters the forming operation zone. The viscosity range of this zone is (4.25-5.57)log P. If the glass melt passes through this process for at least 60 minutes, the glass melt exhibits a special glass material characteristic that does not produce crystallization.

[0156] In this embodiment, the application of a glass product with an atomically precise network structure includes, but is not limited to, omitting natural gas as the heating material for glass melting and using all-electric melting heating as the heating material. This can produce unexpected technical effects such as large-scale energy savings and significant cost reduction.

[0183] An application of a glass fiber product with an atomically precise network structure manufacturing feature includes: the invention newly discovers a new property of the three-dimensional network structure of the atomically manufactured glass product; in the application of glass fiber, the glass melt of the invention, when entering the viscosity logarithmic range of (2.5-2.7)log P, corresponds to a temperature of 1520℃-1230℃; the invention also discovers that the glass melt of the glass material of the invention, when the crystallization temperature is higher than the glass forming temperature or lower than the glass forming temperature, after passing through the drawing holes in the drawing disc, can produce a daily number of glass fiber filaments that are greater than 95% of the number of drawing holes; and it possesses the new material filament-forming properties of ultra-high alumina glass fiber with a high level of sophistication.

[0184] This includes applications of glass fiber in electronics; applications of glass fiber in aerospace, marine, and low-altitude economic applications; applications of glass fiber in automobiles; applications of glass fiber in wind turbine blades; applications of glass fiber in hydrogen energy storage devices or gaseous hydrogen storage devices; and applications of glass fiber in special cement.

[0185] This includes the application of the glass fiber and metal composite material of the present invention in components and shells of vehicles, ships and aircraft.

[0186] In applications of glass fiber, this invention can produce new material properties with a fracture toughness of 0.8-1.6 (MPa*m1 / 2) and an elastic modulus of 80-200 Gpa.

[0187] In the embodiments, the cerium oxide content may be 0.5%, 0.5-1%, 1-2%, or 2-9%.

[0188] In the embodiments, the glass fiber structure of the present invention, characterized by an atomic-level network structure, contains 0.3-6% zirconium. This zirconium undergoes a phase transition at high temperatures, creating stress within the three-dimensional space of the glass, thus increasing the elastic modulus of the glass. Furthermore, the 0.3-4% zirconium content contributes to a high level of thermal shock resistance, preventing cracking or breakage during rapid temperature changes. Finally, the 1-6% zirconium content, coupled with the fact that its diameter is larger than the wavelength of visible light, contributes to the opacity of the glass, allowing for various product applications.

This can produce unexpected technical effects such as large-scale energy savings and significant cost reduction.

Although this invention has some negative effects compared to the prior art [1] and [2] in some aspects, it has significant positive technical effects in other aspects.

The glass of this invention has a specific chemical composition range, and the disclosed technical features are also different from the background technology, and the technical problems to be solved are also different; 2. This invention newly discovers the new properties of a characteristic glass with atomically precise network structure manufacturing characteristics, low forming zone temperature, and specific glass properties, and new properties of glass materials with low forming zone temperature and special glass properties. Utilizing the new properties, unexpected technical effects such as fracture toughness of 0.8-1.6 (MPa*m1 / 2) and elastic modulus of 80-200Gpa can be produced; 3. This invention newly discovers (including glass products with 13-45% alumina in the above technical solutions); 4. The crystallization temperature of the gradient furnace crystallization experiment newly discovered in this invention is between 1220-830℃, which is significantly lower than the temperature at which the glass melt enters (2.8)log 5. The newly discovered quantitative testing method of this invention can obtain quantifiable data on the length and width of glass properties, and can quantitatively test the new property characteristics of this glass product with low crystallization strength and short material properties. This invention demonstrates that the alkali-free glass product with low forming zone temperature and special glass material properties can overcome and solve the historical technical problem that has plagued the production of high-alumina glass products—namely, the short material properties that make them prone to crystallization and thus hinder normal production—a problem that has long been unsolved.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
