摘要：
The microstructure of lead titanate zirconate and PbTiO3-based ceramics is investigated with thermal waves. The photoacoustic data obtained by a gas-microphone method show the presence of thermal-wave diffraction within the samples. The comparison with scanning electron micrographs allows the influence of the grain size and the volume of the glassy phase on the photoacoustic signal to be determined. The influence of the thermal parameters is also discussed. Analysis of the photoacoustic behavior of the investigated ceramic samples is made using the Opsal-Rosencwaig theory.
