White Fused Aluminum Oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory.
White Fused Aluminum Oxide is made from industrial alumina powder, which is smelted in an electric arc furnace at a temperature of over 2000°C and cooled and crystallized to obtain White Fused Aluminum Oxide grit. White Fused Aluminum Oxide and industrial alumina powder also contain alumina, so why do we need to do this extra work for smelting?
This is because the many excellent characteristics of White Fused Aluminum Oxide come from its α-Al2O3 crystals, while the aluminum content of industrial alumina powder is only about 98%, which not only contains other impurities, but also contains Al2O3 isomers, which can significantly reduce the various properties of corundum materials. Therefore, it is necessary to remove impurities by melting, purify the alumina content, and form α-Al2O3 crystals by re-crystallization.
