Abstract

Bi-Te thermoelectric powder was fabricated by mechanical alloying method for 1 to 10 hours under vacuum in planetary mill. We investigated the properties of mechanically alloyed Bi-Te powder by thermal analysis, X-ray diffractometer and FESEM with EDS Bi-Te raw material was formed to $Bi_2Te_3$ phase at condition over 3.5 hours of mechanical alloying time.
