Description

technical field [0001] The invention relates to a glass and a preparation method thereof, in particular to a high temperature resistant phosphate transparent glass and a preparation method thereof. Background technique [0002] Heat-resistant glass is mostly used in utensils, feeding bottles, experimental beakers, industrial boiler sight glass, mechanical equipment window glass, etc. [0003] Heat-resistant glass is mainly quartz glass. Transparent quartz glass can freely withstand 1100-1200°C, and can be heated to 1400°C for a short time. [0004] Quartz glass is the best among silicate glasses. The raw material used to manufacture quartz glass is mainly crystal, and its composition is high-purity Si0 2 , but the crystal itself is a rare mineral, and its melting temperature is required to be above 1713°C. It consumes a lot of energy and is dangerous to operate. And the melting temperature of silicon oxide is 1713°C, and the vaporization temperature is 2100°C, the differ...
