Blend of fused alumina-zirconia grains with chemical analysis next, in percentages by weight and for a total of 100%, ZrO + HfO2: 45.5%; Al2O3: 46-58%; Additive: 0 - 10%, SiO2: <0.8%; Impurities: <1.2 %. This mixture is remarkable in that it has a content of grains containing inclusions less than 2% and in that the concentration of nodules measured on a section of any grain of the mixture is, in at least 50 % of cases, greater than 500 nodules per mm2. |
