Zirconia Fused Corundum ZA25 & ZA40 For Making Coated Abrasives Products
Zirconia Fused Alumina Introduction
Zirconia Fused Alumina,was made from alumina and Zirconium oxide by melting above 2000 in the electric arc furnace and cooling.
Zirconia Fused Alumina Characteristics
Refractory/Fireproof
Zirconia Fused Alumina contains Zirconium Oxide(ZrO2) and Aluminium Oxide(Al2O3) which are important chemical contents for refractory performance. Ideal material for refractory bricks.
High Strength
Zirconia Fused Alumina has high hardness and strength(about 400N). It’s one of the most hard and strong artificial corundum.
Sharp Grain
Like other corundum, grains of ZA is sharp edged material ideal for cutting, lapping, polishing etc of metal surface.
High Density
Zirconia Fused Alumina has true gravity of about 4.3g/cm3, compared to about 3.9g/cm3 of Brown Fused Alumina and 3.6g/cm3 of White Fused Alumina. And bulk density about 2.2g/cm3 which is also much higher than other corundum. It’s used for heavy duty bonded abrasive products.
