Аннотация: The heat capacities of Pb2V2O7 and Pb-3(VO4)(2) as a function of temperature in the range 350-965 K have been studied by the differential scanning calorimetry method. The C (P) = f(T) curve for Pb2V2O7 is described by the equation C (p) = (230.76 +/- 0.51) + (73.60 +/- 0.50)x10(-3) T - (18.38 +/- 0.54)x10(5) T (-2) in the entire teПоказать полностьюmperature range. For Pb-3(VO4)(2), there is a well-pronounced extreme point in the C (P) = f(T) curve at T = 371.5 K, which is caused by the existence of a structural phase transition. The thermodynamic properties of the oxide compounds have been calculated.
