Corundum (structure)
From Wikipedia, the free encyclopedia
Corundum is the name for a structure prototype in inorganic solids, derived from the namesake polymorph of aluminum oxide (α-Al2O3).[1] Other compounds, especially among the inorganic solids, exist in corundum structure, either in ambient or other conditions. Corundum structures are associated with metal-insulator transition,[2] ferroelectricity,[3] polar magnetism,[4][5] and magnetoelectric effects.
