Product name: Alumina
Description: Alumina (Al2O3), industrial Al2O3 is made from bauxite (Al2O3▪3H2O) and diaspore. High-purity Al2O3 is usually produced by chemical methods. Al2O3 has many isomorphous crystals. As far as we know, there are more than 10 kinds of crystals, three major forms of which are γ-Al2O3, β-Al2O3, and α-Al2O3. They have different structures and properties. They can almost completely convert into α-Al2O3 at a temperature higher than 1300 ° C.
