Brown fused alumina chemical composition

Brown fused alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of vitrified and resin bonded tools, and for lapping,polishin, and sand blasting and sand cleaning.It can be also used to make superior refractory products.
