Abstract[English]
The present invention relates to ceria-stabilized tetragonal polycrystal zirconia ceramics comprising the reaction product of 8 to 12 mol % ceria-stabilized zirconia doped with less than 1 mol% calcium oxide and obtained by sintering at a temperature of 1200°C to 1450°C. Tough, strong, reliable and damage-tolerant ceramics with transformation-induced plasticity are provided.[French]
La présente invention concerne des céramiques de zircone polycristalline tétragonales stabilisées par de l'oxyde de cérium comprenant le produit de réaction de 8 à 12 % en moles de zircone stabilisée par de l'oxyde de cérium dopé avec moins de 1 % en moles d'oxyde de calcium et obtenues par frittage à une température de 1200°C à 1450°C, de céramiques résistantes, fiables et tolérantes aux dommages avec une plasticité induite par la transformation.
