Description

Isobaric specific heat of crystal uranovanadates Ca(VUO6)2 · 8H2O, Ba(VUO6)2 · 4H2O in the temperature range of 10 - 300 K and of M1(VUO6)2 · 5H2O, (M1 = Mg, Ca, Sr, Pb) at 80 -300 K are measured by the method of adiabatic vacuum calorimetry. The functions H0(T) - H0(0), S0(T), G0(T) - H0(T) for all the above-mentioned compounds in the range of 0 - 300 K have been calculated, the standard entropies and Gibbs functions of uranovanadates formation at 298.15 K being calculated as well

Abstract (Russian)

Методом адиабатической вакуумной калориметрии измерена изобарная теплоемкость кристаллических уранованадатов Ca(VUO6)2 · 8H2O, Ba(VUO6)2 · 4H2O в интервале температур 10 - 300 К и M1(VUO6)2 · 5H2O, (M1 = Mg, Ca, Sr, Pb) при 80 - 300 К. Рассчитаны функции H0(T) - H0(0), S0(T), G0(T) - H0(T) всех указанных соединений в интервале 0 - 300 К; вычислены стандартные энтропии и функции Гиббса образования уранованадатов при 298,15 К
