What Is Aluminum oxide?
Aluminum oxide is commonly known as bauxite, chemical formula Al2O3, a white powder that is refractory and insoluble in water. The melting point is 2015 ºC, the boiling point is 2980 ºC, the relative density is 4.0, and the hardness is 8.8. It has different crystal forms, mainly including α and γ Two variants. Aluminum hydroxide can be heated and dehydrated to obtain aluminum oxide. Active alumina is a porous solid, which can adsorb a variety of substances, and is often used as a desiccant, adsorbent and catalyst.

Application Of Aluminum oxide
Aluminum Oxide (Alumina) is the most widely used oxide, chiefly because it is plentiful, relatively low in cost, and equal to or better than most oxides in mechanical properties. Density can be varied over a wide range, as can purity-down to about 90% alumina-to meet specific application requirements. Alumina ceramics are the hardest, strongest, and stiffest of the oxides.
