Description

TECHNICAL FIELD

[0001] The present application relates to a glass material, in particular to a photosensitive glass material with lower dielectric loss. BACKGROUND

[0002] The photosensitive glass material will undergo structural changes inside the glass body under the irradiation of ultraviolet light, generate crystal nuclei, and generate a large number of crystals in the irradiated area after further heat treatment at a certain temperature. The crystallinity of the exposed part is high, the glass color becomes dark, and the transmittance decreases. The unexposed part of the glass will not be crystallized and will remain transparent, so that patterns can be made on the photosensitive glass material by mask exposure.

[0003] With the development of the times, in some electronic products, there are light signal emitting ends and receiving ends, and in the transmission path of the light signal, it is necessary to maintain high transmittance and avoid external light signal interference. Therefore, the photosensitive glass material can be designed according to the needs of the specific light signal channel and shielded from the interference of stray light signals. In the prior art, a coating can be applied to the surface of the glass to achieve the above effect. However, compared to the coating on the surface of the glass, the crystalline region of the patterned photosensitive microcrystalline glass device prepared by using the photosensitive glass material penetrates into the glass matrix, so there is no risk of coating falling off, and the crystalline region in the glass can also avoid external light signal crosstalk, which can improve the detection accuracy of the equipment. The photosensitive glass material in the prior art has high dielectric loss, and the transmission loss of the electrical signal in the glass material is large, which is difficult to meet the use of high-performance electronic equipment and the like.

[0134] In some embodiments of the present application, the crystalline phase (crystal) in the photosensitive glass-ceramic or the photosensitive glass-ceramic product contains a lithium silicate crystalline phase, preferably a lithium metasilicate crystalline phase (Li2SiO3) crystalline phase. 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 glass-ceramic or the photosensitive glass-ceramic product includes only the lithium metasilicate crystalline phase.

[0135] In some embodiments, the weight percentage of lithium metasilicate crystalline phase in the blackened portion of the photosensitive glass-ceramic or photosensitive glass-ceramic article is in the range of 5-50%, preferably in the range of 5-40%, more preferably in the range of 10-30%. In some embodiments, the weight percentage of lithium metasilicate crystalline phase in the blackened portion of the photosensitive glass-ceramic or photosensitive glass-ceramic article 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%, 50%.

[0136] SiO2is a glass former oxide, which forms the skeleton of the glass, has a low dielectric constant and dielectric loss, and is a constituent component of lithium metasilicate in the photosensitive glass-ceramic. When the content of SiO2is less than 65%, the hardness and expansion coefficient of the glass decrease, and the dielectric constant and dielectric loss of the glass increase. When the content of SiO2is higher than 78%, the transmittance of the blackened portion of the photosensitive glass-ceramic and photosensitive glass-ceramic article increases. Therefore, the content of SiO2is in the range of 65-78%, preferably in the range of 68-77%, more preferably in the range of 69.5-75.5%. In some embodiments, 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%, 78% of SiO2may be included.

[0137] Li2O is the main component for the formation of crystals in the photosensitive glass-ceramics and the photosensitive glass-ceramic articles. When the content of Li2O is less than 5%, the crystal content of the photosensitive glass-ceramics or the photosensitive glass-ceramic articles is reduced, and the transmittance of the blackened part is higher. When the content of Li2O is greater than 15%, the Young's modulus and the ball drop test height of the glass are reduced, the refractive index and the dielectric loss of the glass are increased, and the glass of the non-UV exposed part of the photosensitive glass material is prone to crystallization during the heat treatment process, and the transmittance of the transparent part of the photosensitive glass-ceramics and the photosensitive glass-ceramic articles is reduced. Therefore, the content of Li2O is limited to 5-15%, preferably 7-13%, and more preferably 8.5-12%. In some embodiments, 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%, 15% of Li2O can be included.

[0138] The inventors have found that in some embodiments, the hardness and the ball drop test height of the glass increase with the increase of the value of SiO2 / Li2O, and the refractive index decreases with the increase of the value of SiO2 / Li2O. At the same time, when SiO2 / Li2O is less than 5.5, the transmittance of the transparent part of the photosensitive glass-ceramics and the photosensitive glass-ceramic articles is reduced, and the transmittance of the blackened part is increased. When SiO2 / Li2O exceeds 10.0, the crystal content of the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramic articles is lower, and the transmittance of the blackened part is increased. Therefore, in some embodiments, it is preferred that SiO2 / Li2O is 5.5-10.0, more preferably SiO2 / Li2O is 6.0-9.0, and further preferably SiO2 / Li2O is 7.0-8.5, the transmittance of the transparent part of the photosensitive glass-ceramics and the photosensitive glass-ceramic articles in the visible light band is higher, and the transmittance of the blackened part is lower, which is particularly suitable for the optical signal channel or the light shielding system of 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.

[0139] Alkali metal oxides R2O (R2O is one or both of Na2O and K2O) can promote the precipitation of lithium metasilicate crystals, improve the transmittance of the blackened portion of the photosensitive glass-ceramics and the photosensitive glass-ceramic article. When the content of R2O is less than 2%, the crystal content of the photosensitive glass-ceramics and the photosensitive glass-ceramic article is reduced, the transmittance of the blackened portion is increased, and the blackening effect cannot even be achieved; when the content of R2O is greater than 12%, the Young's modulus and the ball drop test height of the glass are reduced, and the refractive index, dielectric constant and dielectric loss of the glass are increased. Therefore, the content of R2O is limited to 2-12%, preferably 3-10%, and more preferably 4-8%. In some embodiments, 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%, 12% of R2O can be included.

[0140] Al2O3 can inhibit the reduction of the transmittance of the transparent portion of the photosensitive glass-ceramics and the photosensitive glass-ceramic article after mask exposure and heat treatment, improve the strength and hardness of the glass, and enhance the chemical stability of the glass. When the content of Al2O3 is less than 3%, the hardness and Young's modulus of the glass are reduced, and the linear expansion coefficient is increased; when the content of Al2O3 is greater than 12%, the dielectric constant and dielectric loss of the glass are increased, the crystal content of the blackened portion of the photosensitive glass-ceramics and the photosensitive glass-ceramic article is reduced, the transmittance of the blackened portion is increased, and the blackening effect cannot even be achieved. Therefore, the content of Al2O3 is 3-12%, preferably 4-10%, and more preferably 5-9%. In some embodiments, 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%, 12% of Al2O3 can be included.

[0141] In some embodiments, when 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, and when R2O+Li2O+Al2O3 is greater than 30%, the dielectric constant and dielectric loss of the glass increase. Therefore, it is preferred that R2O+Li2O+Al2O3 be 15-30%, more preferably R2O+Li2O+Al2O3 be 17.5-29.5%, further preferably R2O+Li2O+Al2O3 be 18.5-26%, and more further preferably R2O+Li2O+Al2O3 be 20-25%. 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%, 30%.

[0142] The inventors have found that, in some embodiments, the ratio of the total content of SiO2 and Al2O3 to the total content of Li2O, Na2O and K2O, i.e. (SiO2+Al2O3) / (Li2O+Na2O+K2O), is in the range of 3.0-7.5, the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramics product has a lower transmittance, and the glass has a lower refractive index, which can reduce the reflectivity of the optical signal on the surface of the glass and increase the incidence of the optical signal. Therefore, (SiO2+Al2O3) / (Li2O+Na2O+K2O) is preferably 3.0-7.5, more preferably 3.7-6.5, further preferably 4.3-6.0, and more further preferably 4.8-5.8. In some embodiments, (SiO2+Al2O3) / (Li2O+Na2O+K2O) 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, 7.5.

[0143] ZrO2 can modulate the precision of the blackened part of the glass after mask exposure to form a black pattern, improve the interface distinction of the exposed part and the unexposed part, and prevent the unexposed part from crystallizing near the interface position after heat treatment, thereby maintaining the high transmittance of the transparent part in the visible light band after heat treatment of the unexposed part, while ensuring that the blackened part has a lower transmittance after heat treatment of the exposed part. When the content of ZrO2 is less than 1.5%, the expansion coefficient of the glass increases, and the unexposed part is prone to crystallization during heat treatment of the glass, resulting in a decrease in the transmittance of the transparent part. When the content of ZrO2 is higher than 10%, the crystal content of the photosensitive glass-ceramics and the photosensitive glass-ceramics product decreases, and the transmittance of the blackened part increases, which may even fail to achieve the blackening effect. Therefore, the content of ZrO2 is 1.5-10%, preferably 2-8%, and more preferably 3-6.5%. In some embodiments, the photosensitive glass-ceramics and the photosensitive glass-ceramics product can contain 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%, or 10% of ZrO2.

[0144] In some embodiments, the ratio between the content of K2O+Na2O and the content of ZrO2, (K2O+Na2O) / ZrO2, is controlled in the range of 0.5-7.1, the photosensitive glass-ceramics and the photosensitive glass-ceramic articles have higher transmittance in the transparent part, and the glass has higher hardness and Young's modulus, and lower dielectric constant. Therefore, it is preferred that (K2O+Na2O) / ZrO2 is in the range of 0.5-7.1, more preferably (K2O+Na2O) / ZrO2 is in the range of 0.7-4.5, and further preferably (K2O+Na2O) / ZrO2 is in the range of 0.8-2.5. 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, 7.1.

[0145] In some embodiments, the ratio between the content of Li2O and the content of ZrO2, Li2O / ZrO2, is controlled in the range of 1.0-7.5, the glass has lower refractive index and dielectric loss, and the photosensitive glass-ceramics and the photosensitive glass-ceramic articles have higher transmittance in the transparent part and lower transmittance in the blackened part. Therefore, it is preferred that Li2O / ZrO2 is in the range of 1.0-7.5, more preferably Li2O / ZrO2 is in the range of 1.2-5.0, further preferably Li2O / ZrO2 is in the range of 1.4-4.3, and more further preferably Li2O / ZrO2 is in the range of 1.6-3.0. 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.

[0146] In some embodiments, the ratio between the total content of SiO2and Li2O and the content of ZrO2, (SiO2+Li2O) / ZrO2, is in the range of 8.0-55.0, which can increase the hardness and the ball drop height of the glass, decrease the expansion coefficient and the dielectric constant of the glass, increase the precision of the pattern formed in the photosensitive glass-ceramics and the photosensitive glass-ceramic article after mask exposure and heat treatment, increase the ball drop height of the photosensitive glass-ceramics and the photosensitive glass-ceramic article; the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramic article has a lower transmittance. Therefore, (SiO2+Li2O) / ZrO2 is preferably in the range of 8.0-55.0, more preferably in the range of 10.0-37.0, further preferably in the range of 12.0-25.0, and more further preferably in the range of 13.0-20.0. In some embodiments, (SiO2+Li2O) / ZrO2 can be 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, 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.

[0147] The alkaline earth metal oxide MO (MO is one or more of MgO, CaO, SrO, BaO, ZnO) can improve the dielectric constant of the glass, improve the transmittance of the photosensitive glass ceramic and the blackened portion of the photosensitive glass ceramic article. When the content of MO is higher than 5%, the dielectric constant and dielectric loss of the glass increase, and the Young's modulus and the ball drop test height of the glass decrease. Therefore, the content of MO in the present application is limited to 0-5%, preferably 0-3%, more preferably 0-1%, and further preferably MO is not contained. In some embodiments, the glass can contain 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%, 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% of MO.

[0148] In some embodiments, when MO / ZrO2 is greater than 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 photosensitive glass ceramic and the blackened portion of the photosensitive glass ceramic article increases. Therefore, it is preferred that MO / ZrO2 be 2.5 or less, more preferably MO / ZrO2 be 1.5 or less, and further preferably MO / ZrO2 be 0.5 or less. In some embodiments, the value of MO / ZrO2 can 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, 2.5.

[0149] CeO2 is a photosensitizer, which provides electrons for Ag, Sb, Sn and other components. When the content of CeO2 is lower than 0.01%, it cannot provide enough electrons, resulting in too low crystal content of the photosensitive glass-ceramics, reducing the transmittance of the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramic product, and reducing the Young's modulus of the photosensitive glass-ceramics and the photosensitive glass-ceramic product. When the content of CeO2 is higher than 0.6%, the transmittance of the transparent part of the photosensitive glass-ceramics and the photosensitive glass-ceramic product is reduced, the penetration depth of the photosensitive glass-ceramics and the photosensitive glass-ceramic product in the ultraviolet band is reduced, the crystal content in the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramic product is reduced, and the transmittance is increased. Therefore, the content of CeO2 is 0.01-0.6%, preferably 0.07-0.4%, and more preferably 0.08-0.3%. In some embodiments, 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%, 0.4%, 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% of CeO2 can be included.

[0150] Ag2O as the crystal nucleus agent of the photosensitive glass ceramic and the photosensitive glass ceramic product of the present application plays a role in improving the blackening effect in the photosensitive glass ceramic and the photosensitive glass ceramic product. When the content of Ag2O is less than 0.01%, the transmittance of the blackened part of the photosensitive glass ceramic and the photosensitive glass ceramic product increases, and even the photosensitive glass ceramic and the photosensitive glass ceramic product cannot be blackened, and the drop ball test height of the photosensitive glass ceramic and the photosensitive glass ceramic product decreases, the expansion coefficient increases, and the pattern precision decreases. When the content of Ag2O exceeds 0.8%, the transmittance of the transparent part of the glass decreases during forming or heat treatment, and due to the high content of crystal nucleus, the number of crystals in the photosensitive glass ceramic and the photosensitive glass ceramic product increases, resulting in too fine grain size, the scattering effect of the crystals in the blackened part on visible light is weakened, which easily leads to an increase in the transmittance of the blackened part, and the glass is prone to crystallization during forming. Therefore, the content of Ag2O is limited to 0.01-0.8%, preferably 0.1-0.6%, more preferably 0.2-0.5%. In some embodiments, 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%, 0.4%, 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%, 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% of Ag2O can be included.

[0151] The inventors have found that in some embodiments, by controlling the ratio Ag2O / CeO2 between the content of Ag2O and the content of CeO2 in the range of 1.0-10.0, the grain size of the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramics product is larger, the crystal content is higher, the light scattering effect on the visible light band is stronger, the transmittance of the blackened part is lower, and the hardness and the ball drop test height of the photosensitive glass-ceramics and the photosensitive glass-ceramics product are increased. Therefore, it is preferred that Ag2O / CeO2 is in the range of 1.0-10.0, more preferably Ag2O / CeO2 is in the range of 1.5-6.5, and further preferably Ag2O / CeO2 is in the range of 2.0-4.5.

[0152] In some embodiments, by controlling the ratio ZrO2 / (Ag2O+CeO2) between the content of ZrO2 and the total content of Ag2O and CeO2 Ag2O+CeO2 in the range of 2.3-50.0, the expansion coefficient of the glass can be optimized, the accuracy of the pattern formed in the photosensitive glass-ceramics after the glass is exposed through a mask and heat treated is improved, the transmittance of the transparent part of the photosensitive glass-ceramics and the photosensitive glass-ceramics product is higher, the transmittance of the blackened part is lower, and the hardness and the ball drop height of the glass and the photosensitive glass-ceramics product are increased. Therefore, it is preferred that ZrO2 / (Ag2O+CeO2) is in the range of 2.3-50.0, more preferably ZrO2 / (Ag2O+CeO2) is in the range of 2.5-30.0, and further preferably ZrO2 / (Ag2O+CeO2) is in the range of 3.0-20.0.

[0154] Sb203and Sn02absorb Ce 3+ released electrons during the ultraviolet exposure process, play a role in storing electrons, provide electrons for Ag + during the subsequent heat treatment process, form Ag colloid nucleation, and promote the blackening of the photosensitive glass-ceramics. When the content of Sb203+ Sn02is less than 0.05%, the photosensitive glass-ceramics or photosensitive glass-ceramic product is difficult to achieve blackening. When the content of Sb203+ Sn02is higher than 1.2%, the blackened part of the photosensitive glass-ceramics or photosensitive glass-ceramic product has a tendency to increase in transmittance. Therefore, the content of Sb203+ Sn02is 0.05% to 1.2%, preferably 0.1% to 1%, more preferably 0.2% to 0.7%. In some embodiments, the content of Sb203+ Sn02is 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%, 1.2%.

[0155] Sn02 has a good effect of promoting the blackening of the photosensitive glass-ceramics, but in some embodiments, when the content of Sn02 is higher than 0.5%, the transmittance of the transparent part of the glass is reduced or even lost during the forming or heat treatment. Therefore, the content of Sn02 is limited to 0-0.5%, preferably 0-0.3%, and more preferably 0-0.2%. The content of Sb203 is limited to 0-1%, preferably 0.01-0.7%, and more preferably 0.07-0.5%. In some embodiments, Sn02 can be included at 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%, 0.3%, 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%. In some embodiments, Sb203 can be included at 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%, 0.3%, 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%.

[0156] The inventors have found through a large number of experimental researches that in some embodiments, the ratio between the total content of Sb2O3 and SnO2 and the content of Ag2O, i.e. (Sb2O3+SnO2) / Ag2O, is controlled in the range of 0.1-5.0, which can reduce the dielectric loss of the glass, increase the falling ball test height of the glass and the photosensitive glass-ceramics, and increase the transmittance of the transparent part and reduce the transmittance of the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramics product. Therefore, it is preferred that

[0157] (Sb2O3+SnO2) / Ag2O is 0.1-5.0, more preferably (Sb2O3+SnO2) / Ag2O is 0.5-3.5, and further preferably (Sb2O3+SnO2) / Ag2O is 1.0-2.6.

[0158] In some embodiments, the ratio between the total content of Ag2O, SnO2 and Sb2O3 and the content of CeO2, i.e. (Ag2O+SnO2+Sb2O3) / CeO2, is controlled in the range of 1.0-30.0, which can reduce the transmittance of the blackened part of the photosensitive glass-ceramics and the photosensitive glass-ceramics product, and reduce the dielectric constant of the glass while increasing the hardness and Young's modulus. Therefore, it is preferred that (Ag2O+SnO2+Sb2O3) / CeO2 is 1.0-30.0, more preferably (Ag2O+SnO2+Sb2O3) / CeO2 is 3.0-20.0, further preferably (Ag2O+SnO2+Sb2O3) / CeO2 is 5.0-12.5, and more further preferably

[0159] (Ag2O + Sn02 + Sb203) / Ce02 is 7.5-10.0. In some embodiments, the value of (Ag2O + Sn02 + Sb203) / Ce02 can be 1.0, 1.5, 2.0, 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, 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.

[0160] In some embodiments, the ratio between the total content of Sb203, Sn02, Ce02, Sb203+ Sn02+ Ce02, and the content of Ag2O, (Sb203+ Sn02+ Ce02) / Ag2O, is in the range of 0.1-10.0, which can reduce the dielectric loss and the expansion coefficient of the glass, and make the transmittance of the blackened part of the photosensitive glass ceramic and the photosensitive glass ceramic product lower. Therefore, it is preferred that (Sb203+ Sn02+ Ce02) / Ag2O is 0.1-10.0, more preferably (Sb203+ Sn02+ Ce02) / Ag2O is 0.4-5.0, further preferably (Sb203+ Sn02+ Ce02) / Ag2O is 0.7-3.7, and more further preferably (Sb203+ Sn02+ Ce02) / Ag2O is 1.5-3.2. In some embodiments, the value of (Sb203+ Sn02+ Ce02) / 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, 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, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0.

[0161] In some embodiments, when the value of Sn02 / (Ce02+Sn02) is greater than 0.9, the transmittance of the transparent portion of the glass decreases sharply, or even completely loses transparency, during glass forming or heat treatment. Therefore, it is preferred that Sn02 / (Ce02+Sn02) is 0-0.9, more preferably Sn02 / (Ce02+Sn02) is 0-0.6, further preferably Sn02 / (Ce02+Sn02) is 0-0.5.

When Ln203 is higher than 5%, the transmittance of the blackened portion of the photosensitive glass-ceramics and photosensitive glass-ceramics articles increases, and the dielectric constant and dielectric loss of the glass increase. Therefore, the content of Ln203 is limited to 0-5%, preferably 0-3%, more preferably 0-1%, and in some embodiments, further preferably free of Ln203. In some embodiments, the photosensitive glass-ceramics can contain 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%, 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% of Ln203.

[0163] Fe203 can absorb ultraviolet light during the ultraviolet exposure of the glass, and can be Ag +Fe2O3 is provided to promote blackening of the photosensitive glass-ceramics. When the content of Fe2O3 is higher than 1%, the transmittance of the photosensitive glass-ceramics and the photosensitive glass-ceramics articles in the visible light range decreases, the transmittance of the blackened portion increases, and the drop ball test height of the photosensitive glass-ceramics and the photosensitive glass-ceramics articles decreases. Therefore, the content of Fe2O3 is limited to 0-1%, preferably 0-0.5%, more preferably 0-0.2%, and in some embodiments, further preferably does not contain Fe2O3. In some embodiments, Fe2O3 can be included at 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%, 0.3%, 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%.

[0214] The photosensitive glass material, photosensitive glass-ceramic and photosensitive glass-ceramic article of the present application can be produced and manufactured by the following method:

[0215] The method for manufacturing the photosensitive glass material comprises the following steps: weighing the raw materials according to the component ratio and mixing them uniformly, placing the uniformly mixed raw materials into a platinum or quartz crucible, melting, clarifying and homogenizing at 1450-1600℃, then cooling, pouring the molten glass liquid into a mold, and circulating cooling air to ensure that the glass does not crystallize, preferably preheating the mold to 200-500℃, placing the formed glass and the mold into an annealing furnace for annealing, then cutting off the power and cooling with the furnace to obtain the photosensitive glass material.

[0216] The method for manufacturing the photosensitive glass-ceramic comprises the following steps: forming a photosensitive glass material, treating the photosensitive glass material by a crystallization process, or treating the photosensitive glass material processed into a glass element with a specific shape by a crystallization process, to obtain the photosensitive glass-ceramic. The method for processing the glass element with a specific shape comprises methods known to those skilled in the art, such as hot pressing, grinding or polishing. The crystallization process comprises the following steps: performing a mask exposure treatment on the photosensitive glass material, and then performing a crystallization heat treatment, to uniformly precipitate crystals at the exposed positions of the glass.
