Product Description Brown Aluminium Oxide / Brown Fused ALumina / Brown Corundum 1. Introduction:Brown fused Alumina(also know as brown corundum or brown aluminium oxide) is produced by fusion of calcined bauxite in Electric arc furnaces at high temperature of about 2000 degree celsius. Refractory material:Our brown fused alumina has low iron content making it particularly valuable in refractory applications.Smelted in an electric arc furnace, smelted, desiliconized, iron removed, titanium reduced, and cooled. Abrasive material:BFA has a high refactoriness, is extremely hard and stable.Al2O3 content of brown fused alumina can reach more than 97%, the grinding capacity is 0.1 (diamond is 1).Application:- shaped and unshaped refractory products- abrasive products- blasting medias- brake and friction linings2.
