Etude du comportement thermique de PbSnF4 par analyse calorimetrique differentielle

Abstract The thermal behaviour of PbSnF 4 has been studied by means of a differential scanning calorimeter over the range 298–700 K. Five allotropic forms of PbSnF 4 have been found and the associated enthalpies of transition have been measured. The crystallographic data have been determined for the allotropes by single cristal studies.
