Brown Fused Alumina

Also called brown corundum, the brown fused alumina is a high-grade refractory material. There are two types available in SHUO CHENG.

Product Number: SC-B95
The SC-B95 brown fused alumina is a kind of artificial corundum made by fusing bauxite, carbon material and limatura ferri in a high-temperature electric arc furnace. It is mainly applicable for producing all kinds of corundum series ramming and gunning mixes, castables and refractory bricks.

Product Number: SC-BT95
The SC-BT95 brown fused alumina is fused in a tilting furnace, featuring high purity, great crystallization, strong fluidity, low coefficient of linear expansion and extraordinary corrosion resistance. This kind of synthetic corundum boasts higher toughness and better anti-impact ability, well applicable for making high-quality refractory products.
