BILLES FRITTEES DE ZIRCONE
A sintered bead has a chemical composition, as mass percentages on the basis of the oxides of ZrO2+HfO2+Y2O3+CeO2: balance to 100%; 0%≤Al2O3≤1.5%; CaO≤2%; and oxides other than ZrO2, HfO2, Y2O3, CeO2, Al2O3 and CaO: ≤5%. The contents of Y2O3 and CeO2, as molar percentages on the basis of the sum of ZrO2, HfO2, Y2O3 and CeO2, are such that 1.3%≤Y2O3≤2.5%, in particular 1.3%≤Y2O3<1.8%, and 0.1%≤CeO2≤1.7%, in particular 0.5%≤CeO2≤1.7%, in particular 0.9%<7%, with the proviso that: Y2O3<1.8% with the proviso that 0.5%≤CeO2, and/or 0.9%
