| dc.description.abstract | The manganese hypophosphite monohydrate (α-Mn(H<inf>2</inf>PO<inf>2</inf>)<inf>2</inf>·H<inf>2 </inf>O) was synthesized and characterized by differential thermal analysis-thermogravimetry (TG/DTG/DTA), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The thermal transformation products form the synthesized Mn(H<inf>2</inf>PO<inf>2</inf>)<inf>2</inf>·H<inf>2</inf>O according to the thermal treatment at 160 and 450 °C were found to be α-Mn(H<inf>2</inf>PO<inf>2</inf>)<inf>2</inf>·xH<inf>2 </inf>O and Mn<inf>2</inf>P<inf>2</inf>O<inf>7</inf>, respectively. The activation energies of two decomposition reaction steps of Mn(H<inf>2</inf>PO<inf>2</inf>)<inf>2</inf>·H<inf>2</inf>O were calculated through the isoconversional methods of Ozawa and KAS. The obtained activation energies can be concluded that the reactions of the dehydration and the decomposition steps for Mn(H<inf>2</inf>PO<inf>2</inf>)<inf>2</inf>·H<inf>2</inf>O were the single and multi-step mechanisms, respectively. © 2008 Elsevier Masson SAS.
