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.
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. Our Brown Fused Alumina
Refractory Grades is a high grade refractory material with high purity, high cleanliness, coarse grain, low magnetic
contents, high density, high bulk density, chemical stability, low porosity rate, nice crystal structure, corrosion and
acid resistant. No cracks, corrosion or spot during production of refractory products. Brown Fused Alumina is the
most popular refractory material, especially for refractory bricks.
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.
