Abstract: The experimental observations during sintering of Ce-TZP ceramics in different atmospheres, including nitrogen, argon, air and their mixtures are reported. The O-2 partial pressure was found to strongly influence the fracture toughness of the sintered Ce-TZP material, ranging from 6.6 MPa m(1/2) in air up to 16.2 MPa m(1/2) when sintered in argon. The influence of the oxygen pressure on the microstructure of the Ce-TZP material is elucidated and the increased toughness is explained as a function of the microstructural variables. The presented work reveals that pressureless sintering of CeO2-stabilised powder compacts under a controlled O-2 partial pressure can be used to tune the fracture toughness of Ce-TZP ceramics.
