Study on Preparation of Strong-textured n-type Bismuth Telluride Based Thermoelectric Material by Hot Deformation and its Properties AITranslate
Abstract AITranslate
High-purity raw materials were employed and mixed according to the nominal composition of Bi2Te2.7Se0.3,and then the materials with good crystal orientation were obtained by industrial equipment and zone melting process.Subsequently, the n-type bismuth telluride based alloy with strong texture was obtained by hot deformation process.The above alloy maintains the high power factor of zone-melted crystal rod, and its multi-scale microstructure induced by hot deformation can scatter phonons with wide wavelengths, which effectively reduces the thermal conductivity of the material and significantly increases its thermoelectric figure of merit(ZT).The material was further optimized by doping SbI3.The finally prepared n-type hot-deformed sample has a maximum ZT value of 1.11 at 300 K and an average ZT value of 1.02 in the temperature range of 300~460 K,while its compressive strength is more than three times higher than that of the zone-melted sample.The thermal deformation process optimizes the electrical transport and heat transport performance of bismuth telluride based thermoelectric material, which shows a broad application prospect in the field of power generation from medium and low temperature waste heat.
