“…This loss of water'in two stages was also observed for potassium heptamolybdate tetrahydrate, KsMo7024•4H20, which is isomorphous with ammonium paramolybdate(40).67After the initial loss of the four water molecules of hydration, the reaction proceeds through several molybdate intermediates. This reaction pathway is similar to the polycondensation reactions observed for the decomposition of several molybdates to form molybdenum trioxide(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53); the sample loses Additionally, the MeN product from the diammonium molybdate/ammonia reaction is not converted to Mo2N at temperatures below 75QOC. Therefore, the two nitrides must be produced from the oxynitride in parallel, with the relative rates of reaction depending upon the temperature.The ratio of the two nitride phases in the final product depends upon the final reaction temperature, implying that the ratio of the two nitride phases can be controlled by altering this temperature.…”
