GLASS COMPOSITION FOR HIGH-RELIABILITY CERAMIC PHOSPHOR PLATE AND CERAMIC PHOSPHOR PLATE USING THE SAME

摘要

An embodiment of the present invention relates to a glass composition for a ceramic phosphor plate, which comprises: 75-85 mol% of an oxide mixture containing silicon oxide (SiO_2), boron oxide (B_2O_3), and zinc oxide (ZnO); 10-15 mol% of at least one carbonate mixture including an alkali metal; and 1-5 mol% of aluminium oxide (Al_2O_3). The content of the boron oxide is less than 25 mol%.
