Thermochemistry of Complex Oxides of Uranium(VI), Vanadium(V), Nobium(V) and Alkaline Elements
The determination of the standard enthalpies of formation at 298.15 K of composite oxides of general formula, M(I)VUO(6), where M(I) is Li, Na, K, Rb, Cs, and M(I)NbUO(6), where M(I) is Na, K, Rb, Cs are presented. The standard enthalpies of formation of the crystallohydrates of formula NaVUO6 . 2H(2)O, KVUO6 . 2H(2)O and KNbUO6 . 1.5H(2)O. have also been determined.
