Refractory manufacturing: Refractory alumina powder can be made into a variety of shapes of refractory materials, such as refractory bricks, refractory pipes, ceramic parts, etc., used for high-temperature equipment lining, heat insulation and protection.

Electronic devices: Refractory alumina powder has excellent electrical insulation properties and is widely used in the manufacture of electronic devices, such as semiconductor industry and integrated circuits.

Optical instruments: Refractory alumina powder has high transparency and good anti-wear properties, and is widely used in optical instruments, lenses, optical fibers and other fields.

Chemical, metallurgy: Refractory alumina powder as a catalyst or catalytic carrier, is widely used in chemical and metallurgical fields, such as synthetic ammonia, petroleum processing, etc.

Building materials: Refractory alumina powder can also be used to manufacture building materials, such as high temperature curing agent, special cement and so on.
