Thermoelectric properties of (Bi,Sb)₂Te₃ nanostructured bulk material as a function of composition and spark plasma sintering temperature were investigated. The Bi_0,4Sb_1,6Te₃ alloys at sintering temperature 450—500 °C with ZT=1,25—1,28 figure of merit was fabricated. Thermoelectric properties ad a function of sintering temperature above 400 °C correlate with fine structure change. It was found that point structure defects introduce essential contribution to the formation of nanostructured material thermoelectric properties.
