Photoacoustic Thermal Characterization of Lime-Partially Stabilized Zirconia
Abstract:Photoacoustic and photothermal techniques are used to investigate the room-temperature thermophysical properties of 9.4 mol% lime-partially stabilized zirconia (Ca–PSZ) samples in the density range of 5.12 × 103−5.58 × 103 kg/m3. The open-photoacoustic-cell approach is used to measure thermal diffusivity, and the photothermal technique of continuous illumination of the sample in vacuum is used to measure the product of density and specific heat capacity. Thermal conductivity is shown to be the thermophysical parameter most sensitive to changes in porosity.
