The experiments of DTA, TGA and X-Ray diffraction were carried out to analyse the thermal decomposition kinetics of hydrated aluminum sulfate. The activation energy and order of reaction for the thermal decomposition of hydrated aluminum sulfate were calculated by Freeman's method. The order of reaction and energy of activation in the dehydration reaction were 0.8 and 67.02 kcal/mole, respectively. In the final decomposition reaction with SO₃, evolution, the order of reaction and the activation energy were found to be 1.0 and 105.24 kcal/mole, respectively. The rate equation for the final decomposition reaction was represented.
