ABSTRACT:
Alumina-zirconia lapping abrasives containing tetragonal zirconia at a rate of 30% or less and optionally containing at least one oxide selected from the group consisting of yttrium oxide, calcium oxide, magnesium oxide, titanium oxide and other rare earth oxide in the form of solid solution, which are produced by fusing alumina-zirconia abrasive materials, quenching fused materials to obtain an ingot, crushing the ingot and subjecting the crushed ingot to a heat treatment at a higher temperature than the phase transition temperature of zirconia.
