By method of dynamic calorimetry, in the temperature range between 298,15 and 673 K, isobaric heat capacity of polycrystalline ferrites Bi 2 CaFe 4 O 10 , BVMgFe 2 O 5.5 , BiMgFe 4 O 10 was experimentally studied. Mathematical processing of experimental data made it possible to derive polynomial equation of temperature dependence of ferrites heat capacity for respective temperature ranges, in dependencies C 0 p~f(T) of ferrite Bi2CaFe4O10 a jump was detected in heat capacity at 625K associated with phase transitions of type II. The values of the thermodynamic functions C 0 p (T), H 0 (T) – H 0 (298,15), C 0 (T), F hh (T) have been calculated. Standard values of thermodynamic functions were determined using the method of ion increments. The results obtained broaden thermodynamic data bank for complex inorganic crystalline compounds.
