The heat capacity of solid TbBr3 was measured by differential scanning calorimetry in the temperature range from 300 K up to the melting temperature. The polynomial heat capacity dependence on temperature was used to fit experimental data. Additionally, the temperature and enthalpy of fusion of TbBr3 were also measured. By combination of these results with the literature data on the entropy at 298.15 K, Sm 0 (TbBr3, s, 298.15 K), the standard molar enthalpy of formation, ?formHm 0 (TbBr3, s, 298.15 K), and the heat capacity of the liquid phase, Cp,m 0 (TbBr3, l), the thermodynamic functions of terbium tribromide were calculated up to T ) 1300 K.
