Zirconia Fused Alumina is smelted in the high temperature with Zirconia sand as the main raw material. Its characteristics are good tough texture, dense structure, high intensity, good thermal stability. As a high degree abrasive, it can make high performance grinding wheels to grinding steel, cast iron, metal and all kinds of alloy material. Moreover, Zirconia Fused Alumina is also high degree refractory material and ideal material for producing high performance intake and Zirconia Alumina Brick that makes glass fused kiln.
