Thermophysical Properties of the CsPbCl3 Single Crystal Using Pulse Transient Method1

The main features of the pulse transient method are preseInted. The method gives the specific heat c and thermal diffusivity a for a single measurement, while thermal conductivity * is calculated according to *=ca\, where \ is the density. The pulse transient method is a dynamic method based on the measurement of the temperature response to a heat pulse produced within a specimen. An apparatus operating in the temperature range from &40 to 100%C is described. Errors are discussed. The thermophysical properties of a CsPbCl3 single crystal are determined using the pulse transient method for a temperature range between 10 and 65%C in the controlled heating and cooling regimes. The data show anomalies in the thermophysical properties around the phase transition temperature at 47%C. Discrepancies in comparison with previously published data are discussed.
