Abstract
Alumina-zirconia lapping abrasives containing at most 30% tetragonal zirconia 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 oxides in the form of solid solutions, which are obtainable and preferably obtained 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
