Brown Aluminum Oxide Micro Powder
Brown Aluminum Oxide Powder is made by bauxite, carbon (mainly coke), and iron scrap under high temperature of electric arc furnace.
The mainly ingredient of Brown Aluminum Oxide Micro Powder is Al2O3 ≥ 95%, SiO2 ≤ 1.5%, TiO2 ≤ 3.5%, Fe2O3 ≤ 0.3%. The available grain of brown aluminum oxide micro powder range from F230-F1500, P240-P1500.
Brown Aluminum Oxide Micro Powder performance include High hardness, high strength, impact resistance, high temperature resistance, oxidation resistance, corrosion resistance, low creep, etc. Brown Aluminum Oxide is mainly used as abrasive. Brown Aluminum Oxide Micro Powder is suitable for making bonded and coated abrasive tools, wet or dry blasting, superprecision grinding and polishing, making high quality refractory materials, grinding carbon steel, alloy steel, malleable cast iron, hard bronze and semi-conductor materials.
In recent years, it has been used as the raw material for large and medium-sized blast furnace cast iron hook castables and cast iron aggregates and for the production of common corundum bricks (including high-alumina silicon carbide casts).
