WHITE FUSED ALUMINA
Double click here to add text

It is a high-grade refractory raw material that is made by using high-quality industrial alumina powder after being melted in an electric arc furnace at a high temperature above 2200°C and cooling after the melting, which is also widely used in the abrasive industry.
The main crystal phase is α-Al2O3, and the color is white. The white corundum produced by the tilting electric arc furnace, has the advantages of large volume density and low porosity, thereby improving the volume stability and thermal shock resistance of the material.

  White fused alumina can be used for bonded and coated abrasives, floor wear-resistant sand, ceramic roller professional sand, wet or dry blast sand, suitable for super-precision grinding and polishing in the crystal and electronics industries. It is suitable for processing hardened steel, alloy steel, high-speed steel, high carbon steel and other materials with high hardness and high tensile strength. It can also be used as contact media, insulators and precision casting sand etc. YUFA Group supports various customizations.


White fused alumina is the main raw material for the production of high-grade unshaped and shaped refractory materials. It is widely used in steel, cement,Ceramics, petroleum and other industries, are ideal materials for the production of large-scale ladle casting materials, high-grade iron trench casting materials, spraying materials, prefabricated parts and other unshaped refractory materials and corundum bricks, corundum and mullite corundum saggers, refining The main raw material of various corundum products is corundum porous plug brick, integral spray gun, composite nozzle, high-temperature industrial furnace lining material etc.
