Example Embodiment
[0027] Example 1#:
[0028] The composition of the raw materials is shown in Table 1. The specific preparation process is as follows:
[0029] Weigh the raw materials (20g in total):
[0030]
[0031] Place the weighed raw materials in an agate mortar and fully grind them to form a mixed powder. Place the ground mixed powder in a platinum crucible and put it in a muffle furnace at about 200°C. Preheat for 2-24 hours To remove impurities and moisture. The mixture obtained after preheating was again placed in an agate mortar to fully grind to obtain a uniformly dried powder, and then the prepared powder was placed in a platinum crucible again, and melted in a high temperature furnace exceeding 1100°C for 10 minutes, and then The temperature is raised to not less than 1200℃ and the temperature is maintained for about 60 minutes. After that, the temperature was lowered to about 1100°C and allowed to stand for about 30 minutes. Pour the uniform glass liquid on the preheated cast iron ...

[0037] Example 3#:
[0038] The composition of the raw materials is shown in Table 1. The specific preparation process is as follows:
[0039] Weigh the raw materials (20g in total):
[0040]
[0041] Place the weighed raw materials in an agate mortar and fully grind them to form a mixed powder. Place the ground mixed powder in a platinum crucible and put it in a muffle furnace at about 200°C. Preheat for 2-24 hours To remove impurities and moisture. The mixture obtained after preheating was again placed in an agate mortar to fully grind to obtain a uniformly dried powder, and then the prepared powder was placed in a platinum crucible again, and melted in a high temperature furnace over 1100°C for 10 minutes, and then The temperature is raised to not less than 1200℃ and the temperature is kept for about 60 minutes. After that, the temperature was lowered to about 1100°C and allowed to stand for about 30 minutes. Pour the uniform glass liquid on the preheated cast iron mold, and t...
