Zirconia Fused Aluminum is a kind of high-grade raw material . Using natural zircon sand and bauxite as starting material, it is manufactured by high temperature melting and quenching crystallization. Because of the tough,dense micro-crystalline structure, high strength and good thermal physical, it is used to manufacture high-performance abrasives, abrasives and refractory products.This product has been declared national patent,and advanced high-tech product. It was also awarded the second prize of Scientific and Technological achievement by the Technology Department of Henan province.
