Zirconia-alumina is formed after its mix zircon sand and alumina sand smelted 2000 temperature in electric arc furnace. It's main chemical content is mixture of zirconium dioxide and aluminium oxide.It features compact structure,high toughness,high intensity and high temperature resisting. As a kind of high quality abrasive materials, zirconium corundum can produce high-performance heavy loading grinding wheel, which can grind steel parts, cast iron parts, heat-resistant steel and various alloy materials very well. In addition, Zirconia corundum is also an high grade refractory raw material, it can used for production high-performance sliding nozzle and submerged nozzle ideal material, can also be used for the production of glass furnace zirconium corundum brick.
