Brown fused alumina is fused in the electric arc furnace under the high temperature of above 2200 degrees, with high quality bauxite as main raw material, and through purification, crystallization, cooling, crushing, sorting, magnetic separation, screening and other production technology made into all kinds of particles and powder. 

It is brown and has features of high hardness and toughness. So it is always widely used as material of bonded abrasives such as grinding wheels and cutting wheels, coated abrasives, sand blasting, also for refractory products, chemical additives, precision casting and anti-sliding materials.
