ZA irconia Alumina Abrasive , P20 P220 Zirconium Aluminium Oxide
High Temperature Abrasives Material Zirconum Fused Corundum ZA25 & ZA40 for Bonded and Coated Abarsives
Zirconia Fused Alumina(ZA), other name Zirconium Aluminium Oxide,is an synthetic corundum produced from fusion/smelting high quality alumina powder and zirconia sand in 2000℃ electric arc furnaces. Alumina gives it aluminum oxide and zirconia sand gives it zirconium oxide(ZrO2). After the fusion process, the materials become liquid materials, and crushed (milled)into lump sizes. The lump sizes are then crushed into finer grades or powders and refined by sieving equipment into materials of different particle distribution for different applications. Zirconia Fused Alumina is an important material for abrasive belts, abrasive cloth, heavy duty grinding wheels, refractory and blasting industries used for different applications featuring its high density, high hardness and strength.
