Abstract
Thermoelectric melt spun p-Bi0,5Sb1,5Te3 powders were obtained and their structural properties were
studied. It was established that the crystallites constituting the powder particles are nanofragmented.
Powders were compacted by vacuum hot pressing and spark plasma sintering. Thermoelectric characteris-tics of obtained samples were investigated in 100 K-700 K temperature range. The samples prepared by
above methods posses low thermal conductivity while retaining values of the Seebeck coefficient and elec-trical conductivity comparable to conventional crystallized materials, thereby thermoelectric efficiency ZT
reaches 1.05-1.15 at 330-350 K.
