Resumo

The isobaric heat capacity of double thulium tellurites is studied via dynamic calorimetry in the range of 298.15–673 K. It is used as the basis for deriving the equation Cpof(T) and determining the thermodynamic functions. Dependences Cpof(T) are found to have second-order phase λ-transitions.
