[0023] Embodiment 1: Table 1 shows the glass formula and the first crystallization temperature value of Embodiment 1.
[0024] Table 1
[0025]
[0026] The specific preparation process is as follows: in the first step, weigh 50 grams of analytically pure raw materials according to the formula in Table 1, add 2.5 grams of NH 4 HF 2 , 2.5 g NH 4 HCl 2 , Mix the raw materials evenly and pour them into a quartz crucible to melt, the melting temperature is 1400 ° C, keep warm for 2 hours, pour the glass melt into a cast iron mold, then place it in a muffle furnace for annealing, and keep it at the glass transition temperature Tg for 1 Hours later, cool down to 50°C at a rate of 10°C / hour, turn off the power supply of the muffle furnace to automatically cool down to room temperature, and take out the glass; in the second step, according to the experimental data of thermal analysis (DTA) of the glass, the first crystallization temperature of 780 ℃, put the prepared glass in a...
Embodiment 2
[0028] Embodiment 2: Table 2 shows the glass formula and the first crystallization temperature value of Embodiment 2.
[0029] Table 2
[0030]
[0031] The specific preparation process is as follows: in the first step, weigh 50 grams of analytically pure raw materials according to the formula in Table 2, add 2.5 grams of NH 4 HF 2 , 2.5 g NH 4 HCl 2, Mix the raw materials evenly and pour them into a corundum crucible for melting. The melting temperature is 1460°C and keep warm for 1 hour. Pour the glass melt into a cast iron mold, then place it in a muffle furnace for annealing, and keep warm at the glass transition temperature Tg for 1 hour. Hours later, cool down to 50°C at a rate of 10°C / hour, turn off the power supply of the muffle furnace to automatically cool down to room temperature, and take out the glass; in the second step, according to the experimental data of thermal analysis (DTA) of the glass, the first crystallization temperature of 790 ℃, heat-treat the...
