CERAMIC GRAINS AND PRODUCTION METHOD OF THESE. The invention relates to sintered ceramic grains comprising from 3 to 55% alumina, 40 to 95% zirconia and 1 to 30% of at least one other inorganic component. The invention further relates to a method for preparing ceramic grains comprising: making a slurry comprising alumina, zirconia; making droplets of said slurry; introducing the droplets into a liquid gelling reaction medium in which the droplets are gelled; drying the deformed gelled droplets. |
