Black aluminium oxide is also known as low aluminum corundum. It is also a new type product of polishing material, and it is a dark gray crystal body made Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.

Product Description
Introduction of black fused alumina:
Main functions of black fused alumina:
(1) as there is high temperature, corrosion resistance, high strength properties, it poured with steel sliding gate, smelting rare metals, special alloys, ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers , spark plugs, heat-resistant anti-oxidation coating.
(2) due to high hardness, wear resistance, high strength characteristics, in the chemical system, used for a variety of reaction vessels and pipelines, chemical pump parts; to do mechanical parts, various molds, such as the Roberts mold, extrusion die nozzle pencil lead, etc.; do tool, die grinding, bullet-proof material, the human body joints, sealing ring mold.
(3) corundum insulating materials, such as lightweight corundum brick, corundum hollow ball and fiber products, widely used in a variety of high-temperature kiln furnace walls and roof, both high-temperature insulation again.
