Abstract
We report in this paper a study of the mechanical alloying (MA) process for the Pb 0.65Sn 0.35Te alloy. MA has been carried out in a high-energy planetary ball mill. The mechanism of formation has been studied from systematic analyses of mechanically alloyed powders using X-ray diffraction, differential scanning calorimetry and scanning electron microscopy. As it was already observed for the MA of PbTe, this synthesis is associated with an exothermic reaction between the elemental powders. The required time to reach an homogeneous phase Pb 0..65Sn 0.35Te is 31 h.
