Aluminum oxide
Aluminium oxide is an inorganic substance with the chemical formula Al2O3, is a high-hardness compound with a melting point of 2054 ° C and a boiling point of 2980 ° C. It is an ionic crystal that ionizes at high temperatures and is often used to make refractory materials.
Industrial alumina is made from bauxite (Al2O3·3H2O) and diaspore, for Al with high purity requirements2O3, generally prepared by chemical methods. Al2O3There are many homogeneous crystals, more than 10 known ones, and there are three main crystal forms, namely α-Al2O3、β-Al2O3、γ-Al2O3。Among them, different structures have different properties, and it is almost completely transformed into α-Al at high temperatures above 1300℃.2O3。
