This applies to any possible non-express basis for interpretation, including: logical issues regarding the arrangement of steps, operational flow, order of components, or orientation of components; ordinary meaning derived from grammatical organization or punctuation, and; the number or type of embodiments described in the specification.

[0086] As used herein, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a" component includes aspects having two or more such components unless the context clearly dictates otherwise.

[0087] In embodiments of the glass compositions and resulting colored glass articles described herein, the constituent components (e.g., SiO 2 , Al 2 O 3 The concentrations of olefins (such as olefins) are expressed as mole percent (mol%) based on the oxide unless otherwise stated.

[0088] In the embodiments of the glass compositions and resulting colored glass articles described herein, the concentrations of Au and Cl are expressed as mole percent (mol %) unless otherwise indicated.

[0089] When used to describe the concentration and / or absence of a particular constituent component in a glass composition and a resulting tinted glass article, the term "substantially free" means that the constituent component is not intentionally added to the glass composition and the resulting tinted glass article. However, the glass composition and the resulting tinted glass article may contain trace amounts of the constituent component as a contaminant or impurity in an amount less than 0.1 mol%.

[0090] When used to describe the concentration and / or absence of a particular constituent component in a glass composition and resulting tinted glass article, the terms "0 mol %" and "free of" mean that the constituent component is not present in the glass composition and resulting tinted glass article.

[0091] Fracture toughness (K IC ) represents the ability of a glass composition to resist fracture. Fracture toughness is measured on a non-strengthened glass article, for example, K is measured before the glass article is subjected to ion exchange (IOX) treatment. IC The fracture toughness values ​​are thus characteristic of the glass substrate prior to IOX treatment. The fracture toughness test method described herein is not applicable to glass that has been exposed to IOX treatment. However, fracture toughness measurements made on the same glass (e.g., glass substrate) prior to IOX treatment as described herein are correlated to the fracture toughness after IOX treatment and are therefore used as such. The CNSB method is disclosed in Reddy, KPR et al., "Fracture Toughness Measurement of Glass and Ceramic Materials Using Chevron-Notched Specimens," J. Am. Ceram. Soc., 71[6], C-310-C-313 (1988), except that Y* is calculated using Equation 5 of Bubsey, RT et al., "Closed-Form Expressions for Crack-Mouth Displacement and Stress Intensity Factors for Chevron-Notched Short Bar and Short Rod Specimens Based on Experimental Compliance Measurements," NASA Technical Memorandum 83796, pp. 1-30 (October 1992). m .

[0092] As used herein, the term "liquidus viscosity" refers to the viscosity of a glass composition at the onset of devitrification (ie, at the liquidus temperature measured by a gradient furnace method according to ASTM C829-81).

[0093] Surface compressive stress is measured using a surface stress meter (FSM), such as a commercially available instrument such as the FSM-6000 manufactured by Orihara Industrial Co., Ltd. (Japan). Surface stress measurement relies on the measurement of the stress optical coefficient (SOC), which is related to the birefringence of the glass article. SOC is in turn measured according to Procedure C (Glass Disk Method) described in ASTM Standard C770-16, entitled "Standard Test Method for Measurement of Glass Stress-Optical Coefficient," the contents of which are incorporated herein by reference in their entirety. Depth of Compression (DOC) is also measured using a FSM. Maximum Central Tension (CT) values ​​are measured using a Scattered Light Polarizer (SCALP) technique known in the art.

[0094] As used herein, the term "depth of compression" (DOC) refers to the location in an article where compressive stress transitions to tensile stress.

[0095] As used herein, the term "CIELAB color space" refers to a color space defined by the International Commission on Illumination (CIE) in 1976. It expresses color as three values: L* represents lightness from black (0) to white (100), a* represents from green (-) to red (+), and B* represents from blue (-) to yellow (+).

[0096] As used herein, the term "color gamut" refers to the palette of colors achievable by a tinted glass article within the CIELAB color space.

[0097] As used herein, "optical transmission spectra" are obtained using an Agilent Cary 60 spectrophotometer with a scan range of 250 nm to 800 nm, a scan step of 2 nm, a signal average of 0.5 s, and a spot size of 2 mm. The optical transmission data obtained are used to plot coordinates in the CIELAB color space as described in RS Berns, Billmeyer and Saltzman's Principles of Color Technology, 3rd. Ed., John Wiley & Sons, New York (2000).

[0098] Colorants have been added to conventional aluminosilicate glass compositions to obtain colored glass articles having desired colors and improved mechanical properties. For example, glass articles doped with gold (Au) typically appear red, orange, or purple. However, simply including a colorant in an aluminosilicate glass composition may not produce the desired color.

[0099] Disclosed herein are glass compositions and colored glass articles formed therefrom that mitigate the above-mentioned problems, allowing Au to be added to aluminosilicate glass compositions to produce colored glass articles having a desired color while maintaining excellent ion exchange and drop performance. Specifically, the concentrations of certain constituent components can be adjusted to obtain the desired color and prevent precipitation of Au particles in the glass network.

[0100] The glass compositions and tinted glass articles described herein can be described as aluminoborosilicate glass compositions and tinted glass articles, and include SiO 2 、Al 2 O 3 and B 2 O 3 In addition to SiO 2 、Al 2 O 3 and B 2 O 3 In addition, the glass compositions and colored glass articles described herein further include Au to produce colored glass articles having a desired color. The glass compositions and colored glass articles described herein further include alkali metal oxides, such as Li 2 O and Na 2 O to achieve ion exchangeability of the colored glass product. In addition, the R 2 O and Al 2 O 3 The difference (i.e. R 2 O(mol%)-Al 2 O 3 (mol %)) to produce a desired observable color (e.g., pink, purple, red, or orange). In addition, the viscosity of the glass composition can be adjusted to prevent devitrification of the glass composition and precipitation of Au particles during melting and forming, which can limit the achievable color gamut.

[0101] SiO 2 It is the main glass former in the glass composition described herein and can play a role in stabilizing the network structure of the colored glass product. 2 The concentration of SiO should be sufficiently high (e.g., greater than or equal to 50 mol%) to enhance the chemical durability of the glass composition, and, in particular, the resistance of the glass composition to degradation when exposed to acidic solutions, alkaline solutions, and water. 2 The amount of SiO2 (e.g., limited to less than or equal to 80 mol%) is used to control the melting point of the glass composition, because pure SiO2 2 Or high SiO 2 The melting point of glass is undesirably high. Therefore, the SiO 2The concentration of may help improve the meltability and formability of the resulting colored glass article.

[0102] In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 50 mol % and less than or equal to 80 mol % SiO 2 In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 52 mol % and less than or equal to 75 mol % SiO 2 In an embodiment, the SiO in the glass composition and the resulting colored glass product is 2 The concentration of SiO in the glass composition and the colored resulting glass article may be greater than or equal to 50 mol%, greater than or equal to 52 mol%, greater than or equal to 54 mol%, greater than or equal to 56 mol%, greater than or equal to 58 mol%, or even greater than or equal to 60 mol%. 2 The concentration of SiO in the glass composition and the resulting colored glass article may be less than or equal to 80 mol%, less than or equal to 75 mol%, less than or equal to 73 mol%, less than or equal to 71 mol%, or even less than or equal to 69 mol%. 2The concentration of may be greater than or equal to 50 mol% and less than or equal to 80 mol%, greater than or equal to 50 mol% and less than or equal to 75 mol%, greater than or equal to 50 mol% and less than or equal to 73 mol%, greater than or equal to 50 mol% and less than or equal to 71 mol%, greater than or equal to 50 mol% and less than or equal to 69 mol%, greater than or equal to 52 mol% and less than or equal to 80 mol%, greater than or equal to 52 mol% and less than or equal to 75 mol%, greater than or equal to 52 mol% and less than or equal to 73 mol%, greater than or equal to 52 mol% and less than or equal to 71 mol%, greater than or equal to 52 mol% and less than or equal to 69 mol%, greater than or equal to 54 mol% and less than or equal to 80 mol%, greater than or equal to 54 mol% and less than or equal to 75 mol%, greater than or equal to 54 mol% and less than or equal to 73 mol%, greater than or equal to 54 mol% and less than or equal to 71 mol%, greater than or equal to 54 mol% and less than or equal to 69 mol%, greater than or equal to 56 mol% % and less than 80 mol%, greater than or equal to 56 mol% and less than 75 mol%, greater than or equal to 56 mol% and less than 73 mol%, greater than or equal to 56 mol% and less than 71 mol%, greater than or equal to 56 mol% and less than 69 mol%, greater than or equal to 58 mol% and less than 80 mol%, greater than or equal to 58 mol% and less than 75 mol%, greater than or equal to 58 mol% and less than 73 mol%, greater than or equal to 58 mol% and less than 71 mol%, greater than or equal to 58 mol% and less than 69 mol%, greater than or equal to 50 mol% and less than 80 mol%, greater than or equal to 60 mol% and less than 75 mol%, greater than or equal to 60 mol% and less than 73 mol%, greater than or equal to 60 mol% and less than 71 mol%, or even greater than or equal to 60 mol% and less than 69 mol%, or any and all subranges formed by any of these endpoints.

[0103] Like SiO 2 Same, Al 2 O 3 It can also stabilize the glass network and additionally provide improved mechanical properties and chemical durability to the glass composition and the resulting colored glass article. 2 O 3 The amount of Al may be included to control the viscosity of the glass composition. 2 O 3 , so that the obtained glass composition has a desired fracture toughness (for example, greater than or equal to 0.7 MPa·m 1 / 2 ). However, if Al 2 O 3 If the amount of is too high (eg, greater than 25 mol%), the viscosity of the glass melt may increase, thereby reducing the formability of the colored glass article.

[0104] Thus, in embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 7 mol % and less than or equal to 25 mol % Al 2 O 3 In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 9 mol % and less than or equal to 23 mol % Al 2 O 3 In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 11 mol % and less than or equal to 20 mol % Al 2 O 3 In an embodiment, the glass composition and the resulting colored glass product contain Al 2 O 3 The concentration of Al in the glass composition and the resulting colored glass article may be greater than or equal to 7 mol%, greater than or equal to 9 mol%, greater than or equal to 11 mol%, or even greater than or equal to 13 mol%. 2 O 3 The concentration of Al in the glass composition and the resulting colored glass article may be less than or equal to 25 mol%, less than or equal to 23 mol%, less than or equal to 20 mol%, or even less than or equal to 17 mol%. 2 O 3The concentration of may be greater than or equal to 7 mol% and less than or equal to 25 mol%, greater than or equal to 7 mol% and less than or equal to 23 mol%, greater than or equal to 7 mol% and less than or equal to 20 mol%, greater than or equal to 7 mol% and less than or equal to 17 mol%, greater than or equal to 9 mol% and less than or equal to 25 mol%, greater than or equal to 9 mol% and less than or equal to 23 mol%, greater than or equal to 9 mol% and less than or equal to 20 mol%, greater than or equal to 9 mol% and less than or equal to 17 mol%, greater than or equal to 1 ...%. % and less than 25 mol%, greater than or equal to 11 mol% and less than 23 mol%, greater than or equal to 11 mol% and less than 20 mol%, greater than or equal to 11 mol% and less than 17 mol%, greater than or equal to 13 mol% and less than 25 mol%, greater than or equal to 13 mol% and less than 23 mol%, greater than or equal to 13 mol% and less than 20 mol%, greater than or equal to 13 mol% and less than 17 mol%, or any and all subranges formed by any of these endpoints.

[0105] B 2 O 3 It helps to improve the damage resistance of the resulting colored glass product. 2 O 3 Reduce the formation of non-bridging oxygen. The presence of non-bridging oxygen can reduce the fracture toughness. 2 O 3 The concentration of B should be high enough (e.g., greater than or equal to 1 mol%) to lower the melting point of the glass composition, improve formability, and increase the fracture toughness of the colored glass article. 2 O 3 Too high (eg, greater than 15 mol%), and the annealing point and strain point may be reduced, which increases stress relaxation and reduces the overall strength of the tinted glass article.

[0106] In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 1 mol % and less than or equal to 15 mol % of B. 2 O 3 In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 2 mol % and less than or equal to 12 mol % of B 2 O 3 In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 3 mol % and less than or equal to 10 mol % of B 2 O 3 In an embodiment, the glass composition and the resulting colored glass product have B2 O 3 The concentration of B in the glass composition and the resulting colored glass article may be greater than or equal to 1 mol%, greater than or equal to 2 mol%, greater than or equal to 3 mol%, or even greater than or equal to 4 mol%. 2 O 3 The concentration of B in the glass composition and the resulting colored glass article may be less than or equal to 15 mol%, less than or equal to 12 mol%, less than or equal to 10 mol%, less than or equal to 8 mol%, or even less than or equal to 6 mol%. 2 O 3 The concentration of may be greater than or equal to 1 mol% and less than or equal to 15 mol%, greater than or equal to 1 mol% and less than or equal to 12 mol%, greater than or equal to 1 mol% and less than or equal to 10 mol%, greater than or equal to 1 mol% and less than or equal to 8 mol%, greater than or equal to 1 mol% and less than or equal to 6 mol%, greater than or equal to 2 mol% and less than or equal to 15 mol%, greater than or equal to 2 mol% and less than or equal to 12 mol%, greater than or equal to 2 mol% and less than or equal to 10 mol%, greater than or equal to 2 mol% and less than or equal to 8 mol%, greater than or equal to 2 mol% and less than or equal to 6 mol%, greater than or equal to 3 mol% and less than or equal to 15 mol%, greater than or equal to 3 mol% and less than or equal to 12 mol%, greater than or equal to 3 mol% and less than or equal to 10 mol%, greater than or equal to 3 mol% and less than or equal to 8 mol%, greater than or equal to 3 mol% and less than or equal to 6 mol%, greater than or equal to 4 mol% and less than or equal to 15 mol%, greater than or equal to 4 mol% and less than or equal to 12 mol%, greater than or equal to 4 mol% and less than or equal to 10 mol%, greater than or equal to 4 mol% and less than or equal to 8 mol%, or even greater than or equal to 4 mol% and less than or equal to 6 mol%, or any and all subranges formed by any of these endpoints.

[0107] As described above, the glass composition and the resulting colored glass article may include alkali metal oxides, such as Li 2 O、Na 2 O and K 2 O, to achieve ion exchangeability of colored glass products.

[0108] Li 2 O contributes to the ion exchange capacity of the colored glass product and also lowers the softening point of the glass composition, thereby improving the formability of the colored glass product. 2 O lowers the melting point of the glass composition, which helps improve Au retention. 2The concentration of O in the glass composition and the resulting colored glass article should be high enough (e.g., greater than or equal to 5 mol%) to reduce the melting point of the glass composition and achieve a desired maximum central tension (e.g., greater than or equal to 40 MPa) after ion exchange. 2 If the amount of O is too high (eg, greater than 20 mol%), the liquidus temperature may increase, thereby reducing the manufacturability of the colored glass article.

[0109] In embodiments, the glass composition and resulting tinted glass article may include greater than or equal to 5 mol % and less than or equal to 20 mol % of Li 2 O or 7 mol% or more and 20 mol% or less of Li 2 In embodiments, the glass composition and resulting colored glass article may include greater than or equal to 7 mol % and less than or equal to 18 mol % of Li 2 In embodiments, the glass composition and resulting colored glass article may include greater than or equal to 9 mol % and less than or equal to 16 mol % of Li 2 In embodiments, Li in the glass composition and the resulting colored glass product 2 The concentration of O may be greater than or equal to 5 mol%, greater than or equal to 7 mol%, or even greater than or equal to 9 mol%. In embodiments, the Li 2 The concentration of O may be less than or equal to 20 mol%, less than or equal to 18 mol%, less than or equal to 16 mol%, less than or equal to 14 mol%, or even less than or equal to 12 mol%. In embodiments, the Li in the glass composition and the resulting colored glass article 2The concentration of O can be greater than or equal to 5 mol% and less than or equal to 20 mol%, greater than or equal to 5 mol% and less than or equal to 18 mol%, greater than or equal to 5 mol% and less than or equal to 16 mol%, greater than or equal to 5 mol% and less than or equal to 14 mol%, greater than or equal to 5 mol% and less than or equal to 12 mol%, greater than or equal to 7 mol% and less than or equal to 20 mol%, greater than or equal to 7 mol% and less than or equal to 18 mol%, greater than or equal to 7 mol% and less than or equal to 16 mol%, greater than or equal to 7 mol% and less than or equal to 14 mol%, greater than or equal to 7 mol% and less than or equal to 12 mol%, greater than or equal to 9 mol% and less than or equal to 20 mol%, greater than or equal to 9 mol% and less than or equal to 18 mol%, greater than or equal to 9 mol% and less than or equal to 16 mol%, greater than or equal to 9 mol% and less than or equal to 14 mol%, or even greater than or equal to 9 mol% and less than or equal to 12 mol%, or any and all subranges formed by any of these endpoints.

[0110] Na 2 O improves the diffusion rate of alkali ions in the glass, thereby reducing the ion exchange time and helping to obtain a desired surface compressive stress (e.g., greater than or equal to 300 MPa). Na 2 O also improves the formability of colored glass products. However, if too much Na is added to the glass composition 2 O, the melting point may be too low. Therefore, in embodiments, the Li present in the glass composition and the resulting colored glass article 2 The concentration of O may be greater than the Na present in the glass composition and the resulting colored glass article. 2 The concentration of O.

[0112] K 2 O promotes ion exchange and can increase compression depth and lower melting point to improve the formability of colored glass products. However, adding too much K 2 O may cause surface compressive stress and a too low melting point. Therefore, in an embodiment, K added to the glass composition 2 The amount of O may be limited.

[0113] In embodiments, the glass composition and resulting tinted glass article may include greater than 0 mol % and less than or equal to 1 mol % of K 2 In embodiments, the glass composition and resulting colored glass article may optionally include greater than 0.1 mol % and less than or equal to 0.5 mol % of K 2 In embodiments, the glass composition and the resulting colored glass product contain K 2 The concentration of O may be greater than 0 mol% or even greater than or equal to 0.1 mol%.

[0114] As used herein, R 2 O is present in the glass composition of Na 2 O.K 2 O and Li 2 The total amount of O (in mol%) (i.e., R 2 O=Na 2 O(mol%)+K 2 O(mol%)+Li 2 As described herein, alkali metal oxides such as Na 2 O.K 2 O and Li 2 O helps to lower the softening point and molding temperature of the glass composition, thereby offsetting the 2 The softening point and molding temperature of the glass composition are increased due to a higher amount of alkali metal oxide. The reduction in softening point and molding temperature can be further reduced by including a combination of alkali metal oxides (e.g., two or more alkali metal oxides) in the glass composition, a phenomenon known as the "mixed alkali metal effect". However, it has been found that if the amount of alkali metal oxide is too high, the average thermal expansion coefficient of the glass composition increases to more than 100×10 -7 / ℃, which may not be desirable.

[0142] In embodiments, the glass compositions described herein are ion exchangeable to facilitate strengthening of colored glass articles made from the glass compositions. In a typical ion exchange process, smaller metal ions in the glass composition are replaced or "exchanged" with larger metal ions of the same valence in a layer near the outer surface of a colored glass article made from the glass composition. The replacement of smaller ions with larger ions creates compressive stresses in the layer of the colored glass article made from the glass composition. In embodiments, the metal ions are monovalent metal ions (e.g., Li + , Na + , K + The ion exchange is achieved by immersing a glass article made from the glass composition in a bath of a molten salt containing at least one larger metal ion, which will replace the smaller metal ions in the colored glass article. Alternatively, other monovalent ions such as Ag + , Tl + , Cu + The like can be used to replace monovalent ions. One or more ion exchange methods for strengthening a colored glass article made from a glass composition may include contacting the colored glass article with an ion exchange medium. In an embodiment, the ion exchange medium may be a molten salt bath. For example, the ion exchange process may include, but is not limited to, immersion in a single bath or multiple baths of the same or different compositions, with optional washing and / or annealing steps between immersions.
