Application Number: JP,2024-164077
Category (FI): C03C3/095,C03C3/087,C03C3/085,C03C3/083
Stage: PROBLEM TO BE SOLVED: To provide a photosensitive glass material having a low dielectric loss, a photosensitive crystallized glass made therefrom, a photosensitive crystallized glass product and a method for producing a photosensitive crystallized glass product.SOLUTION: The present invention provides a photosensitive glass material, including the following components in percentage by weight: 65 to 78% of SiO2; 2 to 12% of R2O; 5 to 15% of Li2O; 3 to 12% of Al2O3; 1.5 to 10% of ZrO2; 0.01 to 0.6% of CeO2; 0.01 to 0.8% of Ag2O, wherein Li2O/ZrO2 is 1.0 to 7.5, and the R2O is one or two of Na2O and K2O. By reasonable component design, the photosensitive glass material of the present invention has a lower dielectric loss, and photosensitive crystallized glass and a photosensitive crystallized glass product made therefrom also have lower dielectric losses, and can reduce transmission losses of electric signals of application terminals during use.SELECTED DRAWING: None (Grant)
