Abstract
A correlation analysis of the thermal stability of oxide-based ceramic materials (including partially yttria-stabilized zirconia (PYSZ), beta-alumina, and titanium dioxide) produced in batches by different technologies is carried out. A generalized criterion for thermal stability is proposed that takes into account partial compensation of the thermally generated elastic strain owing to compliant behavior of the network of surface cracks. The criterion provides a satisfactory description of experimental data, allows prediction of the behavior of materials under severe thermomechanical conditions, and suggests ways toward further improvement of material properties.
