White Aluminum Oxide

White aluminum oxide is made with an electric furnace from high-grade alumina powder as main raw material. The resulting mineral has higher hardness and slightly lower toughness than brown fused aluminum oxide. Abrasive tools made of it are very suitable for grinding and polishing of cutting tools. Also it can be used in precision-castings, spraying and blasting, medium body for chemical industry applications, special ceramics and high-grade refractory materials.
