The paper proposes the use of the derivative thermogravimetric (DTG) curve for the acquisition of equilibrium vapor pressure and dissociation pressure for the materials and derivation of their standard enthalpy of formation from single DTG curve recorded under optimum experimental conditions, such as heating rate and the sweep rate of the carrier gas passed over the sample. The vapor pressure and the standard enthalpy of formation ( ' fHo 298.15 ) of CdI2 and the dissociation pressure and the standard enthalpy of formation of CaCO3 derived from their DTG curves are found to be in good agreement with the best assessed values reported in the literature.
