GLASS COMPOSITION FOR PLASMA DISPLAY PANEL, CONTAINING ZnO, B2O3, AND ALKALI EARTH METAL OXIDE AS MAIN COMPONENT AND SMALL AMOUNT OF ADDITIVE, AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: A glass composition and a method are provided to prevent an environmental contamination and achieve improved discharge efficiency. CONSTITUTION: A glass composition comprises ZnO and B2O3 each of which has a ratio of 0.5 to 1.5 and is added by 10 to 40 mol%; an alkali earth metal oxide added by 10 to 25 mol%; Bi2O3 added by 15 mol% or less; and an additive added by 10 mol% or less so as to improve durability of glass and prevent a crystallization. The alkali earth metal oxide is at least one of BaO, CaO, SrO and MgO or a mixture thereof.
