Abstract: The formation process of Mn-Si thermoelectric material made by mechanical alloying followed by pulsed current sintering was investigated. The MA was performed in a planetary ball mill using two elemental powders. The composition of milled powders was MnSi1.85. From the results of thermal analysis by DSC it can be stated that the thermoelectric phase, MnSi1.73, was formed at about 800K. The shrinkage of sintering sample using MA powder during SPS was stagnant at about 800K because of formation of MnSi1.73 phase. Then the shrinkage of sintering sample using MA powder shows a sharp rise at about 900K because the formation of MnSi1.73 was finished. XRD shows the sample sintered at 900K consisted of only MnSi1.73 phase.
