摘要
The heat of the thermal decomposition of monoclini c ammonium paratungstate, (NH4)10H2W12O42· 4H2O, was measured in a HT-1000 microcalorimeter using three-step calorimetry and suitable thermochemical cycle. The standard enthalpy of the thermal decomposition reaction at 298.15 K and the standard enthalpy of formation at 298.15 K for monoclinic ammonium paratung- state were obtained to be (430.1± 10.2) kJ· mol－ 1 and－ (13 423.7± 14.8) kJ· mol－ 1, respectively.
