Calcined Alumina

α-alumina Which Is Applied to Wear-Resistant Ceramics, Electronic Ceramics, Functional Ceramics,

Calcined α-alumina is also called high-temperature alumina. It has a white fine granular appearance. It is calcined at high temperature from industrial aluminum hydroxide or alumina raw materials. It has a high melting point (2053ºC), good thermal stability, and low impurity content , Good electrical insulation; stable crystal structure, acid and alkali corrosion resistance; high hardness (Mohs hardness 9), good wear resistance and other excellent characteristics. Therefore, it is widely used in ceramics, refractory materials, grinding and polishing, petrochemical industries and other industries.
