Product Overview:
White fused alumina is fused by alumina powder by electric arc furnace under high temperature. It has white color and little higher hardness and lower toughness comparing with brown fused alumina. The micro hard- ness of the product is 2200-2300kg/mm2. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s the high-grade refractory materials.
Advantages： The white fused alumina produced by our company has the advantages of high purity, strong self-sharpening, strong grinding force, high efficiency, high temperature resistance and corrosion stability. Abrasive tools made of it have the advantages of sharp grinding, low heat generation rate, high grinding efficiency, and little adhesion during use.

Application：
Abrasive white fused alumina is not only used in abrasive applications but is also a crucial material in the production of refractories due to its high melting point, thermal stability, and chemical resistance. Some of the key refractory uses include:
Kiln and Furnace Linings: WFA is used for manufacturing bricks and linings for high-temperature industrial furnaces, kilns, and reactors. Refractory Castables: White fused alumina is employed in castable refractories that are used in steelmaking and other high-temperature operations. Thermal Insulation: Due to its low thermal conductivity, WFA is also used in insulation materials that are exposed to high temperatures.
