Zirconium corundum is made by using alumina and zirconia as raw materials in an electric arc furnace at a high temperature of 2000 ° C or higher. According to the content of ZrO2, there are generally 25 zirconium corundum (ZrO2 25%) and 40 zirconium corundum (ZrO2 40%). The texture is tough, the structure is dense,

ZA25 Zirconia Fused Alumina is a unique abrasive grit for it’s durable grinding ability. It is not suitable for wear resistance component and sandblasting, but also especially for grinding wheels such as heavey duty grinding wheel,centerless grinding wheel and heavy load cutting disc. ZA25 Zirconia fused alumina is produced from zirconium material and Alumina with a electrofusing process. The

AZ25 is an electro-fused alumina zirconia grain,produced by fusing high grade alumina and zirconia at about 2000 ℃ temperature in an electric arc furnace.And then by quenching,crushing and sizing to the desired grain sizes. This alumina-zirconia(25%) grain consists of the fine primary Corundum as well as ZrO2-Al2O3 eutectic crystalline.This microstructure offers the high intrinsic grain

Zirconia grains has good melt erosion resistance. As a kind of advanced abrasive, it can manufacture high-performance heavy-duty grinding wheel, which has good grinding effect on steel, cast iron, heat-resistant steel and various alloy materials. Zirconium corundum is also an advanced refractory raw material. It is an ideal material for making high-performance sliding nozzles and
