Thermophysical properties of the CsPbCl3 single crystal using pulse transient method

The main features of the pulse transient method are presented. The method g ives the specific heat c and thermal diffusivity cr for a single measuremen t, while thermal conductivity lambda is calculated according to lambda = ca p, where p is the density. The pulse transient method is a dynamic method b ased on the measurement of the temperature response to a heat pulse produce d within a specimen. An apparatus operating in the temperature range from - 40 to 100 degrees C is described. Errors are discussed. The thermophysical properties of a CsPbCl3 single crystal are determined using the pulse trans ient method for a temperature range between 10 and 65 degrees C in the cont rolled heating and cooling regimes. The data show anomalies in the thermoph ysical properties around the phase transition temperature at 47 degrees C. Discrepancies in comparison with previously published data are discussed.
