Thermoelectric Properties of SbTe

Abstract

From the research to determine the thermoelectric properties and crystal structure of SbTe material synthesized by ball mill at 350 rpm for 10 h and sintered with hot press. The hot press method was varied at the time of hot press for 1, 2 and 3 h. The hot press temperature is 400 °C with a pressure of 25MPa. Then all materials were tested by XRD and ZEM 3. Based on the XRD test performed, all materials had hexagonal crystal structures. From ZEM 3 measurement known that the best thermoelectric properties value is in sample 3 which has an electrical resistivity 0.35 mΩcm at 331 K, Seebeck coefficient 147 μV/K at 473 K and power factor 4.53 mW/mK2 at 331 K.
