| Abstract: | 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. |
