Alumina is aluminum oxide (
Al2
O3
), a white, granular material refined from bauxite, commonly used in ceramics, abrasives, and aluminum smelting. It has a high melting point (
∼2
,
050∘C
), high hardness (9 on Mohs scale), and excellent electrical insulation, with purities ranging from 85% to over 99.9%.
