Abstract: Method for producing zirconia-reinforced Al2O3 grains, including at least the following steps: inductively melting a starting mixture to form a eutectic melt made of alumina and zirconia; applying the eutectic melt as a thin layer material, the thin layer material being quenched; and removing the thin layer material. In this manner abrasive grains can be formed directly or the thin layer material can be classified when it is broken into abrasive grains, the grains are polycrystalline without amorphous glass phases as an alumina matrix having zirconia precipitations, and at least some of the zirconia precipitations can be formed in the nanoscale range.
