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 cleaness, coarse grain, low magnetic contents, high density, high bulk density, chemical stability, low prosity rate, nice crystal struction, 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.
Tabular Alumina
Tabular Alumina is a high purity sintered alumina for refractories with Aluminium Oxide(Al2O3) more than 99.8%. It's high temperature resistant, corrosion resistant, anti heat shock, tough, stable in chemical content, good in heat conductivity. After sintered, the aluminum oxide is well crystalized and has high density, low porosity and stable volume. Tabular Alumina we supply has very good particle distribution and is very clean. It's used in many process of steel making industry and also used in ceramic, metallurgical, glass industries.
