Zirconia fused alumina is produced by putting rich aluminum, zirconium materials and additives in electric furnace, smelting with high temperature above 2000°C,cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of tenacious texture, dense structure and high strength.
It is a kind of high grade abrasive and refractory materials, with the characteristic of high intensity, high toughness and high self-sharpness. The most common applications are in high pressure grinding wheels and pressure blasting of very hard surfaces. It is classified into ZA 25 and ZA 40 as the content of Zr02
