α- Al2O3,β- Al2O3,γ- Al2O3,δ- Al2O3 Aluminum oxide powder

Aluminum oxide powder, chemical formula Al2O3. It is a high hardness compound with a melting point of 2054 ℃ and a boiling point of 2980 ℃. It is an ionizable ionic crystal at high temperatures and is commonly used in the manufacture of refractory materials.

Industrial aluminum oxide is prepared from alumina (Al2O3·3H2O) and hard alumina. For Al2O3 with high purity requirements, it is generally prepared by chemical methods. Al2O3 has many homogeneous and heterogeneous crystals, with more than 10 known types, mainly three crystal forms, namely α- Al2O3,β- Al2O3,γ- Al2O3,δ- Al2O3. Among them, the structure and properties are different, and they are almost completely transformed into α- Al2O3.

Aluminum oxide is a stable oxide of aluminum, with the chemical formula Al2O3. Also known as bauxite in mining, ceramics, and materials science.
