ABSTRACT
The structure of Ba5(MnO4)3Cl is refined by the Rietveld method (space group P63/m). The heat capacities of Ba5(MnO4)3Cl apatite were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6-348) K. The experimental data were used to calculate standard thermodynamic functions, namely the heat capacity Cpdeg.(T), enthalpy Hdeg.(T) - Hdeg.(0), entropy Sdeg.(T) - Sdeg.(0) and Gibbs function Gdeg.(T) - Gdeg.(0), for the range from (0 to 350) K.
