Brown Fused Alumina (BFA)

Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites in electric arc furnaces. Brown fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding. Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity. Brown Fused Alumina Refractory Grades is a mineral with fine particle distribution for shaped and unshaped refractory products in fire-proof, precision casting, foundry and coating industries.

Divided by the furnace used during fusion, Brown Fused Alumina can be divided into Fixed Furnace and Tilting Furnace. Tilting Furnace BFA has higher Aluminium Oxide( Al2O3) content and strength, lower impurities. Tilting Furnace BFA can be identified by content of Silicon Oxide( SiO2), with 1%max SiO2, while Fixed Furnace usually with 1.5%max.
