Abstract. Mechanical grinding followed by pulse discharge sintering was applied to fabricate n-type Bi 43 Se 4 Te 53 thermoelectric materials. Calorimetric measurements demonstrated that a Se-rich phase was developed from Bi 2 (Se, Te) 3 phase after 10h of milling. However, when the milling time was extended to 25 h or longer, a Te-rich phase was formed.
