The Effect of Hot Extrusion on the Structure and Thermoelectric Properties of Bi2Te3 Material

Year: 2007

Type: article

Abstract: Bismuth telluride material was fabricated using hot extrusion. The crystal structure was identified by X-ray diffraction and Scanning electron microscopy. The oriented texture in extrusion direction was formed. All the samples showed high mechanical strength. The thermoelectric properties were determined by measuring electrical resistivity, Seebeck coefficient and thermal conductivity. The influence of extrusion temperature on the thermoelectric performence was studied. The variation of figure with temperature was also studied. The oriented texture seems promising to improve thermoelectric properties and mechanical strength.
