Brown alumina 
Brown Fused Aluminum Oxide (A)

Brown alumina is made of high-quality bauxite as the main raw material, which is smelted and crystallized in a dumping electric arc furnace at a high temperature above 2000°C, and then crushed and shaped by an air-fall autogenous mill, magnetically separated, and screened. It has dense texture, high hardness, good self-sharpness, strong grinding force, and equal-area shape of particles. It is suitable for manufacturing ceramics, resin abrasive tools, grinding, polishing, and sandblasting, and can also be used as a high-grade refractory material.
