Brown fused alumina is made by high quality bauxite as main material, fusing and purifying in a pouring electrical at a temperature of over 2200 °, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc. It is hard and tough material, can be widely used as coating abrasive ——Sand paper.
High hardness, crystallinity, good fluidity, little adhesion, no detenate, crack, and pulverization during use
