Black corundum, also known as black fused alumina, is a kind of gray-black crystal with α-Al2O3 and iron spinel as the main ore phase . Black corundum are produced by melting aluminum bauxite in an electric arc furnace in a high temperature. For its high hardness and toughness characteristic, t can be used for mental like stainless steel sandblasting.
