Abstract (en)
[origin: WO2022122515A1] Disclosed is a fused grain having the following chemical composition, expressed in percentages by mass on the basis of the oxides: ZrO2+HfO2: 2% to 13%; elements other than ZrO2, HfO2, Y2O3 and AI2O3: ≤ 2%. Y2O3 + AI2O3: made up to 100%; with 0.0065 ≤ Y2O3/(ZrO2+HfO2) ≤ 0.1300.
