Patent ID: 10723657

Abstract:
Sintered product having a chemical analysis such that, in percentage by mass based on the oxides: ZrO2 partially stabilized with CeO2 and Y2O3 is balance to 100%; Al2O3 is >10% and <19%; additive chosen from CaO, manganese oxides, ZnO, praseodymium oxides, SrO, copper oxides, Nd2O3, BaO, iron oxides, and mixtures thereof is 0.2-6%; impurities are <2%; and CeO2 and Y2O3 being present in amounts such that, as a molar percentage on the basis of the sum of ZrO2, CeO2 and Y2O3, CeO2 is ≥2.5 mol % and <5.5 mol %, and Y2O3 is 0.5-2 mol %.
