Abstract
In this paper, comprehensive studies of the thermophysical properties of the SiGe semiconductor material are carried out in the general temperature range from 200 to 1200°C. The phase transition temperatures are determined by differential scanning calorimetry. The temperature dependences of the heat capacity and the temperature coefficient of linear expansion are given. The density of the studied samples is measured by hydrostatic weighing and gas pycnometry. A comparative analysis of the obtained measurement results is carried out and the methodological features of the experiments are shown.
