A　series　of　p　type　bulk　(Bi0.25Sb0.75)(2)Te-3　thermoelectric　materials　were　prepared　by　melt　spinning-mechanical　milling　(MM)　and　spark　plasma　sintering　(SPS).　Electrical　conductivity,　Seebeck　coefficient　and　thermal　conductivity　of　the　sintered　samples　were　measured　in　the　temperature　range　from　300K　to　523K.　The　effects　of　milling　time　on　thermoelectric　properties　were　investigated　in　system.　The　results　show　that,　with　the　extension　of　milling　time,　the　electrical　conductivity　of　the　sample　increases　and　then　decreases,　Seebeck　coefficient　changes　little,　while　the　thermal　conductivity　decreases　with　the　increase　of　milling　time.　As　a　result,　the　bulk　milled　for　20h　has　the　highest　ZT　value　0.96　at　room　temperature,　meanwhile　the　bending　strength　reaches　91MPa.
