Product Description

ALUMINA POWDER
 

INDUCTION

Derived from aluminum oxide (Al2O3), alumina powder is a high-purity, granular substance that is extensively applied in various industries. It is a white, crystalline powder that is usually manufactured by refining bauxite. Characterized by its hardness, resistance to chemical reactions, and electrical insulation, alumina powder is a sought-after material in many sectors.

It is frequently employed in the fabrication of ceramics, refractory items, and abrasives, and is also integral to the production of a variety of electronic components, including insulators, substrates, and semiconductor parts.

APPLICATION

Alumina powder like brown corundum, when used as porcelain, alumina can be divided into two kinds of forged alumina and ordinary industrial alumina, forged alumina is usually used as the slope material required for the production of antique ceramic tiles, while industrial alumina can be used to produce microcrystalline ceramic tiles, in the traditional porcelain glaze, alumina is usually used as a whitening slope material. As ancient porcelain and microcrystalline ceramic tiles are favored by the market, the use of alumina is gradually increasing.
