Product Description

Brown Fused Alumina,also calleded Brown Fused Aluminium Oxide,Brown Aluminum Oxide or Brown Corundum,named by its mainly brown color, is an artificial electro fused corundum obtained from reduced fusion of high quality bauxite together with other raw materials in 2000℃ electric arc furnaces. Bauxite used for producing of BFA contains high Aluminium Oxide(Al2O3). After the fusion process, the materials are mixed and fused into liquid materials, then cooled down and crushed(milled)into lump sizes. The lump sizes are then crushed into finer grades or powders and refined by sieving equipment into materials of different particle distribution for different applications.
