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 Typical Chemical
Aluminum Zirconia products are hard, very tough, sharp abrasives. They are available in both 25% and 40% zirconia content and produced by fusing zircon sand with alumina at about 1900°C. Alumina Zirconia 25% is used primarily for producing large grinding wheels for foundry snagging and track grinding. It is also an excellent blasting material for
Process of Production and application : Fused Alumina-Zirconia is produced in a high temperature electrical arc furnace by fusing zirconium quartz sand and alumina. It is characterized by hard dense structure, high toughness, good thermal stability. It’s suitable for manufacturing large grinding wheels for steel conditioning and foundry snagging, coated tools and stone blasting, etc.
Zirconia Fused Alumina(Zirconium Fused Aluminium Oxide) is made of Alumina and Zirconia smelted under above 2000 celcius degree, then cooled down and crushed and milled to get angular abrasives material with high strength, toughness and temperature resistence. Zirconia Fused Alumina is an ideal material for high quality abrasies. Zirconium Oxide can manufacturer abrasive and High-performance heavy-duty
Applications: ZA25 is widely used in production of the overload big hot pressed steel condition wheels.
