The results of the investigation on thermal decomposition of CuSO4 · 5H2O under the non-isothermal conditions are presented. The measurements were carried out at the following heating rates: 2, 4, 6, 8 and 10 [K/min]. The mass of the used samples was about 30mg. The process occurred in five steps. Three of them were associated with dehydration and the two of them with the decomposition of the anhydrous salt. The dependencies of the conversion degree on temperature were determined for every stage of the process. They were the basis of the presented quantitative description . The Coats and Redfern equation was applied. The g(alpha) function (kinetic model) of the best accuracy for the individual step and the kinetic parameters of the Arrhenius equation were determined. The identification of the kinetic models was carried out by means of the artificial neural networks. A and E coefficients were evaluated using statistical methods. The described conversions were assumed as stochastic processes.
