Abstract

Bismuth antimony telluride is the most commonly used commercial thermoelectric material for power generation and refrigeration over the temperature range of 200 - 400 K. Improving the performance of these materials is complected balance of optimizing thermoelectric properties. Decreasing the grain size of Bi_0.5Sb_1.5Te₃significantly reduces the thermal conductivity due to the scattering phonons on the grain boundaries. In this work, it is shown the advances of spark plasma sintering (SPS) for preparation of nanocrystalline p-type thermoelctrics based on Bi_0.5Sb_1.5Te₃at different temperatures (240, 350, 400°C). The complex study of structural and thermoelectric properties of Bi_0.5Sb_1.5Te₃were presented. The high dimensionless thermoelectric figure of merit ZT ∼ 1 or some more over 300 - 400 K temperature range for nanocrystalline p-type Bi_0.5Sb_1.5Te₃was obtained.
