Black Aluminum Oxide
Black aluminium oxide is an abrasive that's one among the toughest minerals available. Black aluminium oxide is made through the electrofusion of bauxite, iron oxide and micro-elements during a tilting arc furnace. It can be produced in a variety of sizes from grains to micro-powders and is one of the most economical media available for a wide collection of dry and wet processing applications.
Aluminum oxide is insoluble in water. Its most usually occurring crystalline form, called corundum or α-aluminium oxide. Its hardness makes it suitable for use as an abrasive and as an element in cutting tools. Aluminum oxide is bound for the resistance of metallic aluminium to weathering.
