Thermal conductivity of Al2O3-ZrO2 composite ceramics
Original language description
Al2O3-ZrO2 ceramics were prepared by slip casting and sintered at 1350 °C. The composition of prepared samples varied from pure alumina to doped zirconia (3Y-TZP) with steps of 10 vol.%. The relative density of the sintered samples varied from 94 to 98 %, depending on the composition. Thermal diffusivity of sintered samples was measured by means of the xenon-flash method at 100, 200, 400, 600, 800 and 1000 °C and thermal conductivities were calculated based on measured bulk densities and specific heat data and finally corrected for porosity effects. As expected, the thermal conductivity decreased with increasing zirconia content, and in the case of samples with higher alumina content it also decreased with increasing temperature. Effective thermal conductivities are close to the lower Hashin-Shtrikman bound and the recently proposed sigmoidal average. Empirical relations were used to fit the dependence of effective thermal conductivity of Al2O3-ZrO2 ceramics on both composition and tem
