Zirconia fused alumina oxide abrasives was made from aluminum and Zirconium oxide by melting above 2000 in the electric arc furnace and cooling.Then the huge Zirconia fused alumina oxide abrasives lump be crushed into different size,from a few mm to 0.8 um.
Zirconia fused alumina is strong but pliable in texture,compact structure,Good Thermal Stability.
Generally Zirconia fused alumina is gray color.
