| Abstract: | The heat capacity of Pb2MgTeO6 is measured in the temperature range 80–300 K. It is found that the heat capacity exhibits an anomaly associated with the phase transition at T 0=186.9 K. The thermodynamic parameters of the structural transformation are determined. The effect of hydrostatic pressure up to 0.5 GPa on the phase transition temperature is examined. |
