Embodiment 1-6
[0060] Weigh each component according to the glass composition shown in Table 1, mix well, pour the batch into a platinum crucible, then heat in a high-temperature furnace at 1600°C for 5 hours, and stir with a platinum rod to remove air bubbles. The melted glass is poured into a stainless steel mold to form a specified block glass product, and then the glass product is annealed in the annealing process for 1 hour, and then the power is turned off and the furnace is cooled to room temperature. The glass product is cut, ground and polished, then cleaned with high-purity water and dried to obtain a finished glass product with a thickness of 0.6mm. Various properties of each glass product were measured respectively, and the results are shown in Table 1.
