In this work, the chemical analysis of the initial and activated shale from the Kendyrlyk deposit of Kazakhstan is described. The activated shale was obtained in the high-temperature processes of carbonization and activation in the atmospheres of argon and water vapor, respectively. The electrophysical characteristics of the test shale were determined for first time by measuring the electrocapacity of samples in a temperature range of 293–483 K. The temperature dependences of the specific heat of shale were obtained by dynamic calorimetry. Based on the experimental data, equations for the temperature dependence of the heat capacity of shale were derived; these equations can be subsequently used for determining the thermal conductivity and thermal diffusivity of shale.
