Glass composition with high elasticity and heat resistance

摘要: PURPOSE: To enhance elasticity and heat resistance to enable spinning into a filament by blending prescribed percentages of SiO 2 , Al O 3 MgO, CaO, TiO BaO, SrO, R oxide rare earth element. CONSTITUTION: The titled composition consists of, weight, 45W70% 20W35% 2W17% 6W21% CaO (MgO+CaO=10W23%), 0W6% 0W10% BaO+SrO, 0W1% O, element ≤1% impurities. This glass has high is easily spun filament. COPYRIGHT: (C)1983,JPO&Japio
