High alumina fine powder is widely used in the production of refractory materials such as refractory bricks, refractory cement and refractory castables. Its high hardness and wear resistance make it an ideal material to resist high temperature wear. In addition, high-aluminum fine powder also has excellent fire resistance and can withstand extremely high temperatures, so it is widely used in high-temperature industrial environments.
