Calcined Alumina 100 mesh - 0.4 UM
Introduction:
Alumina (Aluminium oxide), chemical formula Al2O3, is a high-hardness compound with a melting point of 2054℃, a boiling point of 2980℃, and ionic crystals that can be ionized at high temperatures. It is commonly used in the manufacture of refractory materials.
Alumina is a stable oxide of aluminum and its chemical formula is Al2O3. It is also called bauxite in mining, ceramics and materials science. And it is a White solid insoluble in water, odorless, tasteless, extremely hard, easy to absorb moisture without deliquescence (burnt does not absorb moisture).
Alumina is divided into calcined alumina and ordinary alumina, calcined alumina is an essential raw material for the production of antique brick, and can be used in the production of alumina ceramic stone, in traditional glaze, alumina is used as a whitening. As the antique brick and microcrystalline stone has been favored by the market, the amount of alumina is also increasing year by year.
Therefore, alumina ceramic in the ceramics industry came into being - alumina ceramic is a kind of Al O as the main raw material, the main crystalline phase with corundum ceramic material. Because of its high mechanical strength, high hardness, high dielectric loss, high temperature and high insulation resistance, chemical corrosion resistance and good thermal conductivity and excellent comprehensive technical performance advantages
