[0056] Weigh the components as shown in Table 1, mix them well, pour the mixture into a platinum crucible, and then heat it in a resistance furnace at 1430°C for 4 hours, and stir with a platinum rod to expel bubbles. Pour the molten glass into a stainless steel cast iron grinding tool and shape it into a specified block glass product. Then, the glass product is annealed in an annealing furnace for 2 hours. The power is turned off and the furnace is cooled to 25°C. Cut, grind, and polish the glass product, and clean the surface of the polished 50*50*1mm glass product with deionized water and put it into 420℃ molten KNO 3 It is treated for 3 hours, then taken out and cooled to 25°C, cleaned with deionized water and dried to obtain a glass product. The various properties of each glass product were measured, and the results are shown in Table 1.
