Brown Fused Alumina(BFA),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 2000ºC 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.
BFA Characters
Refractory/Fireproof
Brown Fused Alumina contains 94%-97% Aluminium Oxide(Al2O3) which makes it an material which resists high temperature,corrosion and has good thermal conductivity. It is an ideal raw mineral for shaped and unshaped refractory products and fireproof products, especially in steel making industry.
High Strength
Brown Fused Alumina contains Al2O3 and little content of Titanium Oxide(TiO2) and Iron Oxide(Fe2O3) and is a very tough material with 9 grade mosh hardness. This character makes it good for cutting, abrasives, polishing, lapping of various materials and can be used durably and recycled.
Sharp Grain
During fusion, Brown Fused Alumina is made a crystal material with sharp edges and ideal for durable grinding, polishing and abrasives.During blasting industry, BFA grains are used as a blasting media to prepare surface of metal,ceramic,wood and other materials.
High Density
Brown Fused Alumina is a dense material with high bulk density and true gravity. It is used as a material in casting and water purifying processes.
