Brown Fused Aluminum Oxide for Refractory
Brown Fused Alumina is an important synthetic corundum refractory mineral made from reduced fusion of quality
bauxite, iron and coal in electric arc furnace under 2500 degree. It's hard, tough, dense, fire-proof, sharp-edged,
wear resistant, and corrosion resistant material and widely used in production of grinding wheels, sand papers,
sand cloth, sanding belt, production of refractory bricks, steel making industry, ceramic, glass, cement industry etc.
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.
We also have Barmac equipment for mill of Brown Fused Alumina to improve its shape by centrifugal force. BFA
milled by Barmac equipment is granted more round shape grits and higher bulk density. Refractory products made
of it will have higher density and strength, and also less opportunity to have cracks.
