Brown fused alumina is a kind of artificial corundum produced by high temperature smelting of natural bauxite. Although the main component is Aluminium Oxide, it still contains a lot of other chemical components such as silica, iron oxide, titanium oxide, etc.

We loading Brown Fused Alumina 22# 24# 46# 54# yesterday, and they will be shipping to to France soon.

Brown fused alumina shows blue after calcination at 1350℃ temperature. The impurities existed in the grains will be separated out & vaporized . The surface of each particle changes coarser, improves the hydrophilicity greatly. After 1350℃ calcinations ,cracks from crushing and crystal cooling proces

High resistance to polishing, abrasion and weathering*Chemical stability under acid/alkali agents and intense heat applications

About Brown Fused Aluminum Oxide Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength.
