摘要：

Phase transition and thermal decomposition of [Cd(H2O)6](BF4)2 were studied by differential scanning calorimetry (DSC), differential thermal analysis (DTA) and thermogravimetry (TG) methods. The solid-solid phase transition at TC1=324 K and the melting point atTmelt.=391 K were registered. The thermal dehydration process starts just above TC1 and continues up to Tmelt.,where [Cd(H2O)4](BF4)2 in the liquid phase is formed. Then, dehydration and decomposition take place simultaneously until CdF2 is obtained. Final products of the thermal decomposition were identified using quadrupole mass spectrometry (QMS) and X-ray diffraction methods.
