Description

[Technical Field]

[0001] The present invention relates to glass materials, and more particularly to photosensitive glass materials with low dielectric loss. [Background technology]

[0002] When photosensitive glass material is irradiated with ultraviolet light, structural changes occur within the glass body, causing crystal nuclei to form. When heat treatment is continued at a certain temperature, a large amount of crystals are produced in the irradiated area. The exposed area has a high degree of crystallization, the glass color becomes darker, and the transmittance decreases, while the unexposed area remains transparent without crystallizing. Therefore, a pattern can be created in the photosensitive glass material by mask exposure.

[0003] With the development of modern electronic products, some electronic products have optical signal transmitting and receiving ends. The optical signal transmission path must maintain high transmittance while avoiding interference from external optical signals. Photosensitive glass materials can be used to design specific optical signal channels as needed to shield stray optical signal interference. While conventional techniques can achieve this effect by applying a coating to the glass surface, patterned photosensitive crystallized glass devices manufactured using photosensitive glass materials have crystalline regions embedded deep within the glass matrix, eliminating the risk of coating loss. Furthermore, crosstalk between external optical signals can be avoided even in the crystalline regions within the glass, thereby improving the detection accuracy of the device. However, conventional photosensitive glass materials have high dielectric loss, resulting in significant transmission loss of electrical signals within the glass material, making them unsuitable for use in high-performance electronic devices.

[0089] In some embodiments of the present invention, the crystalline phase (crystals) in the photosensitive crystallized glass or photosensitive crystallized glass product contains a lithium silicate crystalline phase, preferably a lithium metasilicate crystalline phase (LiSiO). In some embodiments, the lithium metasilicate crystalline phase has a higher weight percentage than other crystalline phases. In some embodiments, the crystalline phase in the photosensitive crystallized glass or photosensitive crystallized glass product comprises only the lithium metasilicate crystalline phase.

[0090] In some embodiments, in the blackened portion of the photosensitive crystallized glass or photosensitive crystallized glass product, the weight percentage of the lithium metasilicate crystalline phase is 5 to 50%, preferably the weight percentage of the lithium metasilicate crystalline phase is 5 to 40%, and more preferably the weight percentage of the lithium metasilicate crystalline phase is 10 to 30%. In some embodiments, the weight percentage of the lithium metasilicate crystalline phase in the photosensitive glass-ceramic or darkened portion of the photosensitive glass-ceramic product is 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, or 50%.

[0091] SiO2 is a glass-forming oxide, a structural component of the glass, with low dielectric constant and dielectric loss. SiO2 is a component of lithium metasilicate in photosensitive crystallized glass. If the SiO2 content is less than 65%, the hardness and expansion coefficient of the glass decrease, and the dielectric constant and dielectric loss of the glass increase. If the SiO2 content exceeds 78%, the transmittance of the blackened portions of the photosensitive crystallized glass and photosensitive crystallized glass products increases. Therefore, the SiO2 content range is 65 to 78%, preferably 68 to 77%, and more preferably 69.5 to 75.5%. In some embodiments, the composition may comprise about 65%, 65.5%, 66%, 66.5%, 67%, 67.5%, 68%, 68.5%, 69%, 69.5%, 70%, 70.5%, 71%, 71.5%, 72%, 72.5%, 73%, 73.5%, 74%, 74.5%, 75%, 75.5%, 76%, 76.5%, 77%, 77.5%, or 78% SiO2.

[0092] Li2O is the main component that forms crystals in the photosensitive crystallized glass and photosensitive crystallized glass product of the present invention. If the Li2O content is less than 5%, the crystal content of the photosensitive crystallized glass or photosensitive crystallized glass product will be reduced, resulting in increased transmittance in the blackened areas. If the Li2O content exceeds 15%, the Young's modulus and ball drop test height of the glass will decrease, the refractive index and dielectric loss of the glass will increase, and the glass will be more susceptible to crystallization during heat treatment in areas not exposed to UV light during crystallization of the photosensitive glass material, resulting in decreased transmittance in the transparent areas of the photosensitive crystallized glass and photosensitive crystallized glass product. Therefore, the Li2O content is limited to 5-15%, preferably 7-13%, and more preferably 8.5-12%. Some embodiments may include about 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, or 15% LiO.

[0093] The inventors have found through research that in some embodiments, as the SiO2 / Li2O ratio increases, the hardness and ball drop test height of the glass increase, and as the SiO2 / Li2O ratio increases, the refractive index decreases. Furthermore, when the SiO2 / Li2O ratio is less than 5.5, the transmittance of the transparent portion of the photosensitive glass-ceramics and photosensitive glass products decreases, while the transmittance of the darkened portion increases. When the SiO2 / Li2O ratio exceeds 10.0, the crystalline content of the darkened portion of the photosensitive glass-ceramics and photosensitive glass products decreases, and the transmittance of the darkened portion increases. Therefore, in some embodiments, when SiO2 / Li2O is preferably 5.5 to 10.0, more preferably 6.0 to 9.0, and even more preferably 7.0 to 8.5, the transparent parts of the photosensitive crystallized glass and photosensitive crystallized glass products have high transmittance in the visible light wavelength range, while the blackened parts have low transmittance, making them particularly suitable for optical signal channels or light-shielding systems in electronic products. In some embodiments, the value of SiO2 / Li2O can be 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 9.0, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 10.0.

[0094] Alkali metal oxides R2O (R2O is one or both of Na2O and K2O) promote the precipitation of lithium metasilicate crystals and improve the transmittance of the blackened areas of photosensitive crystallized glass and photosensitive crystallized glass products. If the R2O content is less than 2%, the crystal content of the photosensitive crystallized glass and photosensitive crystallized glass products will decrease, the transmittance of the blackened areas will increase, and the blackening effect will not be achieved. If the R2O content exceeds 12%, the Young's modulus and ball drop test height of the glass will decrease, and the refractive index, dielectric constant, and dielectric loss of the glass will increase. Therefore, the R2O content is limited to 2-12%, preferably 3-10%, and more preferably 4-8%. In some embodiments, the composition may contain about 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, or 12% R2O.

[0095] Al2O3 can suppress the decrease in transmittance of the transparent portions of photosensitive crystallized glass and photosensitive crystallized glass products after mask exposure and heat treatment, improve the strength and hardness of the glass, and enhance the chemical stability of the glass. If the Al2O3 content is less than 3%, the hardness and Young's modulus of the glass will decrease and the linear expansion coefficient will increase. If the Al2O3 content exceeds 12%, the dielectric constant and dielectric loss of the glass will increase, the crystalline content of the blackened portions of the photosensitive crystallized glass and photosensitive crystallized glass products will decrease, the transmittance of the blackened portions will increase, and the blackening effect will not be achieved. Therefore, the Al2O3 content is 3 to 12%, preferably 4 to 10%, and more preferably 5 to 9%. Some embodiments may include about 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, or 12% Al2O3.

[0096] In some embodiments, if the total content of R2O, Li2O, and Al2O3 (R2O + Li2O + Al2O3) is less than 15%, the refractive index, hardness, and Young's modulus of the glass decrease, while if R2O + Li2O + Al2O3 exceeds 30%, the dielectric constant and dielectric loss of the glass increase. Therefore, preferably, R2O + Li2O + Al2O3 is 15 to 30%, more preferably, R2O + Li2O + Al2O3 is 17.5 to 29.5%, even more preferably, R2O + Li2O + Al2O3 is 18.5 to 26%, and even more preferably, R2O + Li2O + Al2O3 is 20 to 25%. In some embodiments, R2O + Li2O + Al2O3 is about 15%, 15.5%, 16%, 16.5%, 17%, 17.5%, 18%, 18.5%, 19%, 19.5%, 20%, 20.5%, 21%, 21.5%, 22%, 22.5%, 23%, 23.5%, 24%, 24.5%, 25%, 25.5%, 26%, 26.5%, 27%, 27.5%, 28%, 28.5%, 29%, 29.5%, or 30%.

[0097] As a result of intensive experimental research, the inventors have found that in some embodiments, by controlling the ratio (SiO2+Al2O3) / (Li2O+Na2O+K2O) of the total content of SiO2 and Al2O3 (SiO2+Al2O3) to the total content of Li2O, Na2O, and K2O (Li2O+Na2O+K2O) within the range of 3.0 to 7.5, the transmittance of the blackened part of the photosensitive crystallized glass and photosensitive crystallized glass product can be lowered, and the refractive index of the glass can be lowered, thereby reducing the reflectance of optical signals on the glass surface and improving the incidence rate of optical signals. Therefore, preferably, (SiO2+Al2O3) / (Li2O+Na2O+K2O) is 3.0 to 7.5, more preferably, (SiO2+Al2O3) / (Li2O+Na2O+K2O) is 3.7 to 6.5, even more preferably, (SiO2+Al2O3) / (Li2O+Na2O+K2O) is 4.3 to 6.0, and even more preferably, (SiO2+Al2O3) / (Li2O+Na2O+K2O) is 4.8 to 5.8. In some embodiments, the value of (SiO2 + Al2O3) / (Li2O + Na2O + KO) can be 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, or 7.5.

[0098] ZrO2 adjusts the accuracy of the black pattern formed in the blackened area after mask exposure of glass, improves the distinction between the interface between the exposed and unexposed areas, and prevents crystallization near the interfacial separation location after heat treatment of the unexposed area. This ensures that the unexposed area maintains high transmittance in the visible light wavelength range after heat treatment, while ensuring that the blackened area has low transmittance after heat treatment of the exposed area. If the ZrO2 content is less than 1.5%, the expansion coefficient of the glass increases, making the unexposed area more likely to crystallize during heat treatment, and reducing the transmittance of the transparent area. If the ZrO2 content exceeds 10%, the crystal content of the photosensitive crystallized glass and photosensitive crystallized glass product decreases, increasing the transmittance of the blackened area and ultimately failing to achieve the desired blackening effect. Therefore, the ZrO2 content is 1.5-10%, preferably 2-8%, and more preferably 3-6.5%. Some embodiments may include about 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10% ZrO2.

[0099] In some embodiments, by controlling the ratio (K2O+Na2O) / ZrO2 of the total content of K2O and Na2O (K2O+Na2O) to the content of ZrO2 within the range of 0.5 to 7.1, the transmittance of the transparent portion of the photosensitive crystallized glass and photosensitive crystallized glass product is high, the hardness and Young's modulus of the glass are high, and the dielectric constant of the glass is low. Therefore, preferably, (K2O+Na2O) / ZrO2 is 0.5 to 7.1, more preferably, (K2O+Na2O) / ZrO2 is 0.7 to 4.5, and even more preferably, (K2O+Na2O) / ZrO2 is 0.8 to 2.5. In some embodiments, the value of (K2O+Na2O) / ZrO2 can be 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 6.0, 6.5, 7.0, or 7.1.

[0100] In some embodiments, by controlling the ratio of Li2O to ZrO2 (Li2O / ZrO2) within the range of 1.0 to 7.5, the glass can have a low refractive index and dielectric loss, and the precision of forming a pattern in the photosensitive crystallized glass and photosensitive crystallized glass product after mask exposure and heat treatment of the glass can be improved, and the photosensitive crystallized glass and photosensitive crystallized glass product can have high transmittance in the transparent portion and low transmittance in the blackened portion. Therefore, Li2O / ZrO2 is preferably 1.0 to 7.5, more preferably 1.2 to 5.0, even more preferably 1.4 to 4.3, and even more preferably 1.6 to 3.0. In some embodiments, the value of Li2O / ZrO2 can be 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5.

[0101] In some embodiments, by controlling the ratio of the total content of SiO2 and Li2O (SiO2+Li2O) to the content of ZrO2 ((SiO2+Li2O) / ZrO2)) within the range of 8.0 to 55.0, the hardness and ball drop test height of the glass can be improved, the expansion coefficient and dielectric constant of the glass can be reduced, the precision of forming patterns in the photosensitive crystallized glass and photosensitive crystallized glass products after mask exposure and heat treatment of the glass can be improved, the ball drop test height of the photosensitive crystallized glass and photosensitive crystallized glass products can be improved, and the transmittance of the blackened parts of the photosensitive crystallized glass and photosensitive crystallized glass products can be reduced. Therefore, (SiO2+Li2O) / ZrO2 is preferably 8.0 to 55.0, more preferably 10.0 to 37.0, even more preferably 12.0 to 25.0, and even more preferably 13.0 to 20.0. In some embodiments, the value of (SiO2 + Li2O) / ZrO2 is 8.0, 8.5, 9.0, 9.5, 10.0, 10.5, 11.0, 11.5, 12.0, 12.5, 13.0, 13.5, 14.0, 14.5, 15.0, 15.5, 16.0, 16.5, 17.0, 17.5, 18.0, 18.5, 19.0, 19.5, 20.0, 20.5, 21.0, 21.5, 22.0, 22.5, 23.0, 23.5, 24.0, 24.5, 25.0, 25.5, 26.0, 26.5, 27.0, 27.5, 28.0, 28.5, 29.0, 29.5, 30.0, 30.5, 31.0, 31.5, 32.0, 32.5, 33.0, 33.5, 34.0, 34.5, 35.0, 35.5, 36.0, 36.5, 37.0, 37.5, 38.0, 38.5, 39.0, 40.0, 40.5, 41.0, 41.5, 42.0, 42.5, 43.0, 43.5, 44.0, 44.5, 45.0, 45.5, 46.0, 46.5, 47.0, 47.5, 48.0, 48.5, 49.0, 5 .0, 26.5, 27.0, 27.5, 28.0, 28.5, 29.0, 29.5, 30.0, 30.5, 31.0, 31.5, 32.0, 32.5, 33.0, 33.5, 34.0, 34.5, 35.0, 35.5, 36.0, 36.5, 37.0, 38.0, 39.0, 40.0, 41.0, 42.0, 43.0, 44.0, 45.0, 46.0, 47.0, 48.0, 49.0, 50.0, 51.0, 52.0, 53.0, 54.0, 55.0.

[0102] Alkaline earth metal oxides MO (MO is one or more of MgO, CaO, SrO, BaO, and ZnO) can improve the dielectric constant of glass and the transmittance of the blackened parts of photosensitive crystallized glass and photosensitive crystallized glass products. If the MO content exceeds 5%, the dielectric constant and dielectric loss of the glass increase, and the Young's modulus and ball drop test height of the glass decrease. Therefore, the MO content in the present invention is limited to 0-5%, preferably 0-3%, more preferably 0-1%, and even more preferably no MO is contained. In some embodiments, the percentage is about 0%, greater than 0%, 0.01%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.10%, 3.11%, 3.12%, 3.13%, 3.14%, 3.15%, 3.16%, 3.17%, 3.18%, 3.19%, 3.20%, 3.21%, 3.22%, 3.23%, 3.24%, 3.25%, 3.26%, 3.27%, 3.28%, 3.29%, 3.30%, 3.31%, 3.32%, 3.33%, 3.34%, 3.35%, 3.36%, 3.37%, 3.38%, 3.39%, 3.40%, 3.41%, 3.42%, 3.43%, 3.44%, 3.45%, 3.46%, 3.47%, 3.48%, 3.49%, 3.50%, 3.51%, 3.52%, 3.53%, 3.54%, 3.55%, 3.56%, 3.57%, 3.58%, 3.59%, 3.60%, 3.61%, 3.62%, 3.63%, 3.64%, 3 %, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9%, 5% MO may be included.

[0103] In some embodiments, when the MO / ZrO ratio exceeds 2.5, the dielectric loss of the glass increases, the hardness, Young's modulus, and ball drop test height of the glass decrease, and the transmittance of the darkened portion of the photosensitive crystallized glass and photosensitive crystallized glass product increases. Therefore, preferably, the MO / ZrO ratio is 2.5 or less, more preferably, the MO / ZrO ratio is 1.5 or less, and even more preferably, the MO / ZrO ratio is 0.5 or less. In some embodiments, the MO / ZrO ratio may be 0, greater than 0, 0.01, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, or 2.5.

[0104] CeO2 is a photosensitizer that provides electrons to components such as Ag, Sb, and Sn. If the CeO2 content is less than 0.01%, it cannot provide enough electrons, resulting in a too low crystalline content of the photosensitive crystallized glass, which reduces the transmittance of the darkened areas of the photosensitive crystallized glass and photosensitive crystallized glass products, and also reduces the Young's modulus of the photosensitive crystallized glass and photosensitive crystallized glass products. If the CeO2 content is more than 0.6%, the transmittance of the transparent areas of the photosensitive crystallized glass and photosensitive crystallized glass products will decrease, and the penetration depth in the ultraviolet wavelength range of the photosensitive crystallized glass and photosensitive crystallized glass products will decrease, which will reduce the internal crystalline content of the darkened areas of the photosensitive crystallized glass and photosensitive crystallized glass products, thereby increasing the transmittance. Therefore, the CeO2 content is 0.01-0.6%, preferably 0.07-0.4%, and more preferably 0.08-0.3%. In some embodiments, the concentration is about 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, 0.30%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.40%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.50%, 0.51%, 0.52%, 0.53%, 0.54%, 0.55%, 0.56%, 0.57%, 0.58%, 0.59%, 0.60%, 0.61%, 0.62%, 0.63%, 0.64%, 0.65%, 0.66%, 0.67%, 0.68%, 0.69%, 0.70%, 0.71%, 0.72%, 0.73%, 0.74%, 0.75%, 0.76%, 0.77%, 0.78%, 0.79%, 0.80%, 0.81%, 0.82%, 0.83%, 0.84%, , 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.4%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.5%, 0.51%, 0.52%, 0.53%, 0.54%, 0.55%, 0.56%, 0.57%, 0.58%, 0.59%, 0.6% CeO2.

[0105] AgO serves as a crystal nucleating agent in the photosensitive crystallized glass and photosensitive crystallized glass products of the present invention, improving the blackening effect of the photosensitive crystallized glass and photosensitive crystallized glass products. If the AgO content is less than 0.01%, the transmittance of the blackened areas of the photosensitive crystallized glass and photosensitive crystallized glass products will be high, resulting in the inability to blacken, and the photosensitive crystallized glass and photosensitive crystallized glass products will have a reduced ball drop test height, an increased expansion coefficient, and reduced pattern accuracy. If the AgO content exceeds 0.8%, the transmittance of the transparent areas will be reduced during glass molding or heat treatment, and the content of crystal nuclei will be too high, resulting in an increased number of crystals in the photosensitive crystallized glass and photosensitive crystallized glass products and excessively fine crystal grain size. This will weaken the visible light scattering effect of the crystals in the blackened areas, increasing the transmittance of the blackened areas and making the glass more susceptible to crystallization during molding. Therefore, the content of Ag2O is limited to 0.01 to 0.8%, preferably 0.1 to 0.6%, and more preferably 0.2 to 0.5%. In some embodiments, the concentration is about 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.40%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.50%, 0.51%, 0.52%, 0.53%, 0.54%, 0.55%, 0.56%, 0.57%, 0.58%, 0.59%, 0.60%, 0.61%, 0.62%, 0.63%, 0.64%, 0.65%, 0.66%, 0.67%, 0.68%, 0.69%, 0.70%, 0.71%, 0.72%, 0.73%, 0.74%, 0.75%, 0.76%, 0.77%, 0.78%, 0.79%, 0.80%, 0.81%, 0.82%, 0.83%, 0.84%, 0 , 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.5%, 0.51%, 0.52%, 0.53%, 0.54%, 0.55%, 0.56%, 0.57%, 0.58%, 0.59%, 0.6%, 0.61%, 0.62%, 0.63%, 0.64%, 0.65%, 0.66%, 0.67%, 0.68%, 0.69%, 0.7%, 0.71%, 0.72%, 0.73%, 0.74%, 0.75%, 0.76%, 0.77%, 0.78%, 0.79%, 0.8% AgO.

[0106] As a result of research, the inventors have found that in some embodiments, by controlling the ratio of Ag2O content to CeO2 content, Ag2O / CeO2, within the range of 1.0 to 10.0, the crystal grain size of the blackened portion of the photosensitive crystallized glass and photosensitive crystallized glass product becomes larger, the crystal content becomes higher, the scattering effect for light in the visible wavelength range becomes stronger, the transmittance of the blackened portion becomes lower, and the hardness and ball drop test height of the photosensitive crystallized glass and photosensitive crystallized glass product increase. Therefore, Ag2O / CeO2 is preferably 1.0 to 10.0, more preferably 1.5 to 6.5, and even more preferably 2.0 to 4.5. In some embodiments, the value of Ag2O / CeO2 can be 1.0, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0.

[0107] In some embodiments, by controlling the ratio ZrO2 / (Ag2O+CeO2) of the ZrO2 content to the total content Ag2O and CeO2 (Ag2O+CeO2) within the range of 2.3 to 50.0, the expansion coefficient of the glass can be optimized, and the precision of forming a pattern in the photosensitive crystallized glass after mask exposure and heat treatment of the glass can be improved. In addition, the transparent parts of the photosensitive crystallized glass and photosensitive crystallized glass products have high transmittance and the blackened parts have low transmittance, and the hardness and falling ball height of the glass and photosensitive crystallized glass products can be improved. Therefore, ZrO2 / (Ag2O+CeO2) is preferably 2.3 to 50.0, more preferably 6.5 to 35.0, even more preferably 8.5 to 20.0, and even more preferably 11.0 to 18.0. In some embodiments, the value of ZrO2 / (Ag2O+CeO2) is 2.3, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0, 10.5, 11.0, 11.5, 12.0, 12.5, 13.0, 13.5, 14.0, 14.5, 15.0, 15.5, 16.0, 16.5, 17.0, 17.5, 18.0, 18.5, 19.0, The size may be 19.5, 20.0, 20.5, 21.0, 21.5, 22.0, 22.5, 23.0, 23.5, 24.0, 24.5, 25.0, 26.0, 27.0, 28.0, 29.0, 30.0, 31.0, 32.0, 33.0, 34.0, 35.0, 36.0, 37.0, 38.0, 39.0, 40.0, 41.0, 42.0, 43.0, 44.0, 45.0, 46.0, 47.0, 48.0, 49.0, or 50.0.

[0108] Sb2O3 and SnO2 react with Ce during UV exposure. 3+ It absorbs electrons emitted from Ag and stores them during subsequent heat treatment. +This provides electrons to the photosensitive glass-ceramics, forming nuclei for Ag colloids and promoting the darkening of the photosensitive glass-ceramics. If the Sb2O3 + SnO2 content is less than 0.05%, the photosensitive glass-ceramics or photosensitive glass-ceramics products will have difficulty achieving the desired darkening effect. If the Sb2O3 + SnO2 content exceeds 1.2%, the transmittance of the darkened portions of the photosensitive glass-ceramics or photosensitive glass-ceramics products will tend to increase. Therefore, the Sb2O3 + SnO2 content is 0.05-1.2%, preferably 0.1-1%, and more preferably 0.2-0.7%. In some embodiments, the Sb2O3 + SnO2 content is about 0.05%, 0.1%, 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 0.55%, 0.6%, 0.65%, 0.7%, 0.75%, 0.8%, 0.85%, 0.9%, 0.95%, 1.0%, 1.05%, 1.1%, 1.15%, or 1.2%.

[0109] SnO2 is highly effective in promoting the blackening of photosensitive glass-ceramics, but in some embodiments, if the SnO2 content exceeds 0.5%, the transmittance of the transparent portion decreases during molding or heat treatment of the glass, leading to devitrification. Therefore, the SnO2 content is limited to 0-0.5%, preferably 0-0.3%, and more preferably 0-0.2%. The Sb2O3 content is limited to 0-1%, preferably 0.01-0.7%, and more preferably 0.07-0.5%. In some embodiments, the percentage is about 0%, greater than 0%, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, 0.30%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.40%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.50%, 0.51%, 0.52%, 0.53%, 0.54%, 0.55%, 0.56%, 0.57%, 0.58%, 0.59%, 0.60%, 0.61%, 0.62%, 0.63%, 0.64%, 0.65%, 0.66%, 0.67%, 0.68%, 0.69%, 0.70%, 0.71%, 0.72%, 0.73%, 0.74%, 0.75%, 0.76%, 0.77%, 0.78%, 0.79%, 0.80%, 0.81%, 0.82%, 0.83 It may contain 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.4%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, or 0.5% SnO2. In some embodiments, the percentage of glycerin in the blood is about 0%, greater than 0%, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, or greater than about 0%. %, 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.4%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.5%, 0.55%, 0.6%, 0.65%, 0.7%, 0.75%, 0.8%, 0.85%, 0.9%, 0.95%, 1% Sb2O3.

[0110] Through extensive experimental research, the inventors have found that, in some embodiments, controlling the ratio of the total content of Sb2O3 and SnO2 (Sb2O3 + SnO2) to the content of Ag2O ((Sb2O3 + SnO2) / Ag2O) within the range of 0.1 to 5.0 reduces the dielectric loss of the glass, improves the ball drop test height of the glass and photosensitive crystallized glass products, and ensures high transmittance in the transparent portions and low transmittance in the darkened portions of the photosensitive crystallized glass and photosensitive crystallized glass products. Therefore, preferably, (Sb2O3 + SnO2) / Ag2O is 0.1 to 5.0, more preferably, 0.5 to 3.5, and even more preferably, 1.0 to 2.6. In some embodiments, the value of (Sb2O3 + SnO2) / Ag2O can be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0.

[0111] In some embodiments, by controlling the ratio (Ag2O+SnO2+Sb2O3) / CeO2 of the total content of Ag2O, SnO2, and Sb2O3 (Ag2O+SnO2+Sb2O3) to the content of CeO2 within the range of 1.0 to 30.0, the transmittance of the blackened parts of the photosensitive crystallized glass and photosensitive crystallized glass product can be reduced, the dielectric constant of the glass can be lowered, and the hardness and Young's modulus can be improved. Therefore, preferably, (Ag2O+SnO2+Sb2O3) / CeO2 is 1.0 to 30.0, more preferably, (Ag2O+SnO2+Sb2O3) / CeO2 is 3.0 to 20.0, even more preferably, (Ag2O+SnO2+Sb2O3) / CeO2 is 5.0 to 12.5, and even more preferably, (Ag2O+SnO2+Sb2O3) / CeO2 is 7.5 to 10.0.

[0112] In some embodiments, by controlling the ratio (Sb2O3+SnO2+CeO2) / Ag2O of the total content of Sb2O3, SnO2, and CeO2 (Sb2O3+SnO2+CeO2) to the content of Ag2O within the range of 0.1 to 10.0, the dielectric loss and expansion coefficient of the glass can be reduced, and the transmittance of the blackened parts of the photosensitive crystallized glass and photosensitive crystallized glass products can be lowered. Therefore, preferably, (Sb2O3 + SnO2 + CeO2) / Ag2O is 0.1 to 10.0, more preferably, (Sb2O3 + SnO2 + CeO2) / Ag2O is 0.4 to 5.0, even more preferably, (Sb2O3 + SnO2 + CeO2) / Ag2O is 0.7 to 3.7, and even more preferably, (Sb2O3 + SnO2 + CeO2) / Ag2O is 1.5 to 3.2.

[0113] In some embodiments, if the value of SnO2 / (CeO2+SnO2) exceeds 0.9, the transmittance of the transparent portion of the glass will drop sharply during glass molding or heat treatment, eventually resulting in complete devitrification. Therefore, preferably, SnO2 / (CeO2+SnO2) is 0 to 0.9, more preferably, SnO2 / (CeO2+SnO2) is 0 to 0.6, and even more preferably, SnO2 / (CeO2+SnO2) is 0 to 0.5.

[0114] Ln2O3 (Ln2O3 is one or more of La2O3, Gd2O3, and Y2O3) can adjust the dielectric constant and dielectric loss of the glass, and Ag +This can provide electrons to the glass, accelerating the darkening of the photosensitive glass-ceramics. If the Ln2O3 content exceeds 5%, the transmittance of the darkened portions of the photosensitive glass-ceramics and photosensitive glass-ceramics products increases, and the dielectric constant and dielectric loss of the glass increase. Therefore, the Ln2O3 content is limited to 0-5%, preferably 0-3%, more preferably 0-1%, and in some embodiments, even more preferably no Ln2O3 is contained. In some embodiments, the Ln2O3 content is about 0%, more than 0%, 0.01%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2%, 2.1%, 2.2%, 2.3%. , 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9%, 5% Ln2O3.

[0115] Fe2O3 can absorb ultraviolet light during ultraviolet exposure of glass, and Ag +This can provide electrons to the photosensitive glass-ceramics, accelerating the darkening of the photosensitive glass-ceramics. If the Fe2O3 content exceeds 1%, the transmittance of the transparent portions of the photosensitive glass-ceramics and photosensitive glass-ceramics products within the visible light wavelength range decreases, the transmittance of the darkened portions increases, and the ball drop test height of the photosensitive glass-ceramics and photosensitive glass-ceramics products decreases. Therefore, the Fe2O3 content is limited to 0-1%, preferably 0-0.5%, more preferably 0-0.2%, and in some embodiments, it is even more preferable that Fe2O3 is not contained. In some embodiments, the percentage of glycerin in the blood is about 0%, greater than 0%, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.21%, 0.22%, 0.23%, 0.24%, 0.25%, 0.26%, 0.27%, 0.28%, 0.29%, or greater than about 0%. %, 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39%, 0.4%, 0.41%, 0.42%, 0.43%, 0.44%, 0.45%, 0.46%, 0.47%, 0.48%, 0.49%, 0.5%, 0.55%, 0.6%, 0.65%, 0.7%, 0.75%, 0.8%, 0.85%, 0.9%, 0.95%, 1% Fe2O3.

[0116] The terms "not contained" and "0%" used in the present specification refer to compounds, molecules, elements, etc. that are not intentionally added to the photosensitive glass material, photosensitive crystallized glass, or photosensitive crystallized glass product of the present invention as raw materials. However, there may be some impurities or components that are not intentionally added to the raw materials and / or equipment used to manufacture the photosensitive glass material, photosensitive crystallized glass, or photosensitive crystallized glass product, and these may be contained in small or trace amounts in the final photosensitive glass material, photosensitive crystallized glass, or photosensitive crystallized glass product; such situations are also within the scope of the claims of the present invention.

[0117] Each performance index of the photosensitive crystallized glass and / or photosensitive crystallized glass product and / or photosensitive glass material of the present invention is measured by the following method.

[0118] <Light transmittance> The light transmittance was measured as follows: the sample to be measured was processed to a certain thickness, the opposing surfaces were buffed parallel to each other, and the light transmittance was measured in accordance with the Chinese national standard "GB / T 7962.12-2010."

[0119] <Linear expansion coefficient> Linear expansion coefficient (α 20℃~300℃ ) was measured at 20° C. to 300° C. in accordance with the Chinese national standard "GB / T 7962.16-2010." In the present invention, the linear expansion coefficient may be abbreviated to the expansion coefficient.

[0120] <Dielectric constant> Dielectric constant (ε r ) was measured in accordance with the Chinese national standard "GB / T 7265.1-1987" and data was measured under the condition of 1 GHz.

[0121] <Dielectric loss> The dielectric loss (tan δ) was measured in accordance with the Chinese national standard "GB / T 7265.1-1987," and the data was measured under the condition of 1 GHz.

[0122] <Dropping ball test height> A 20mm diameter x 1mm sample was placed on a glass mounting jig and a 32g steel ball was dropped from a predetermined height. The maximum impact the sample could withstand without breaking was determined as the ball drop test height. Specifically, the test was started at a ball drop test height of 100mm. If no breakage occurred, the height was increased in the following order: 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, 700mm, 800mm, 900mm, 100mm, 1000mm, 1100mm, 1200mm, and higher.
