Such materials include silicate materials, ceramics, and refractory materials.
1. Silicate materials: Silicate materials are a material with a long production history, large output, and wide uses, such as cement, glass, ceramics, etc.
2. Ceramic materials: Ceramic materials refer to inorganic non-metallic materials made of clay as the main raw material and fired at high temperatures. They have the characteristics of high hardness and corrosion resistance.
3. Refractory materials: Refractory materials refer to inorganic non-metallic materials that are not easy to melt or lose strength at high temperatures, such as silicon, aluminum silicate, high aluminum, etc.
