dc.description.abstractThe thermal decomposition of synthetic serrabrancaite (MnPO<inf>4</inf> · H<inf>2</inf>O) was studied in N<inf>2</inf> atmosphere using TG-DTG-DTA. Thermal analysis results indicate that the decomposition occurs in two stages, which are assigned to the dehydration and the reduction processes and the final product is Mn<inf>2</inf>P<inf>2</inf>O<inf>7</inf>. X-ray powder diffraction, FT-IR and FT-Raman techniques were used for identification of the solid decomposition product. The decomposition kinetics analysis of MnPO <inf>4</inf> · H<inf>2</inf>O was performed under non-isothermal condition through isoconversional methods of Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS). The dependences of activation energies on the extent of conversions are observed in the dehydration and the reduction reactions, which could be concluded the "multi-step" processes. © Akadémiai Kiadó, Budapest, Hungary 2009.
