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.
