Zirconia Aluminum Oxide(ZA)
Source of zirconium corundum
FUSED ZIRCONIA ALUMINA is FUSED with ALUMINA and ZIRCONIA in an arc furnace at 2000℃.
Classification of zirconium corundum
According to the content of ZrO2, there are generally low zirconium corundum (ZrO2 10%~15%), medium zirconium corundum (ZrO225%) and high zirconium corundum (ZrO2 40%).
Chemical composition of zirconium corundum
Zirconium corundum has main crystal phase of alpha -Al2O3, sub-crystal phase of oblique zircon, and a small amount of glass phase.
Chemical composition (%)
Acuity 68.020.0-27.0 3.00 1.50 or less or less
Physical properties of zirconium corundum
Zirconium corundum is characterized by its strong texture, dense structure, high strength and good thermal shock.
Use of zirconium corundum
Zirconium corundum has good corrosion resistance to melt. As an advanced abrasive material, it can produce high performance heavy load grinding wheel. In addition, zirconium corundum is a kind of high quality refractory material, which is ideal for making high performance sliding and immersion nozzle, and can also be used for making zirconium corundum brick for glass melting kiln.
