Abstract
The applicability of the Thermodynamic Difference Rule to mixed inorganic oxides is assessed for a range of aluminates, borates, ferrites, phosphates, silicates and vanadates. The deviation of the phosphate data from the linear relation between the enthalpy of formation, ΔfH°, of the solid solvating oxide and ΘHf, the Thermodynamic Difference Rule Constant, is discussed and we conclude that the use of ΔfH°(P4O10, s) to provide the solvating oxide data is inappropriate and, instead, a value for ΔfH°(P2O5, s) of −1618 ± 9 kJ mol−1 is proposed.
