Brown Fused Alumina Grit Brown Fused Alumina Oxide For Refractory Raw Material
Brown corundum, also known as carborundum, is a brown artificial corundum made from bauxite, carbon materials and iron shavings in an electric arc furnace. The main chemical composition of brown corundum is AL2O3, its content is 95.00% Fry 97.00%, and contains a small amount of Fe,Si,Ti and so on. Brown corundum is the most basic abrasive, which is widely used because of its good grinding performance, wide range of application and low price.



Brown corundum is a kind of natural non-metallic mineral with island structure, which is mainly used in industry. The color of good iron-aluminum garnet is dark red, with high hardness, good toughness and significant characteristics.As a filter material for water pollution treatment, it has incomparable advantages over other filter media:
1. With a large specific gravity (4.1-4.4g/cm3), there is almost no brown corundum overflow when the sewage treatment tank or water overflows, which improves the efficiency of water pollution treatment.
2. Brown corundum has a polyhedral structure (usually dodecahedron or 38-hedron). Compared with ordinary elliptical or round filter media (activated carbon, sponge iron, manganese sand, etc.), brown corundum has better porosity (bulk density: 2.10-2.23g/cm3) after accumulation, and the filtration effect is obviously better than other filter media.
3. Garnet is a physical treatment method, which contains no free silicon, no heavy metals, no radioactivity and is harmless to human body.
4. Acid and alkali resistance, the solubility in acid and alkali is less than 1%.
5. Natural non-metallic minerals with high hardness (7.5-8.0), low crushing rate and high reuse rate.


Brown Fused Alumina Grit Brown Fused Alumina Oxide For Refractory Raw Material has following usages:
1. Used for manufacturing advanced refractories, castable materials, refractory bricks and so on.
2. Sandblasting.
3. Free grinding
4. Resin abrasives
