The enthalpies of formation of a series of mixed metal oxides, MO/sub y/W/sub 1-y/O/sub 3/ (y = 0.25, 0.5, 0.64, and 0.69), and hydrogen insertion compounds, H/sub 0.54/Mo/sub 0.25/W/sub 0.75/O/sub 3/, H/sub x/Mo/sub 0.5/W/sub 0.5/O/sub 3/ (x = 0.63 and 0.66) and H/sub x/Mo/sub 0.69/W/sub 0.31/O/sub 3/ (x = 0.34, 0.45, and 0.98) have been determined by solution calorimetry. The enthalpies of hydrogen insertion into the mixed oxides are compared to those for the simple oxides MoO/sub 3/ and WO/sub 3/, which have been recalculated. The stability of the insertion compounds toward oxidation is discussed. 16 references, 5 tables.
