Resumo

The molar heat capacity of Pb4V2O9 and Pb8V2O13 in the temperature range 350–1000 K was measured by differential scanning calorimetry. It was determined that the plot Cp = f(T) for Pb8V2O13 has an extremum within the range 416–516 K, which is due to a phase transition. A correlation was found between the heat capacity and composition of oxides in the PbO–V2O5 system. The data obtained allowed one to predict the specific heat capacity value for Pb(VO3)2.
