Abstract

From the research to determine the thermoelectric properties and crystal structure of SbTe material synthesized by ball mill at 350 rpm for 10 hours and sintered with hot press. The hot press method was varied at the time of hot press for 1, 2 and 3 hours. The hot press temperature is 400 °C with a pressure of 25 MPa. 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 mΩ cm at 331 K, Seebeck coefficient 147 uV/K at 473 K and power factor 4.53 mW/mK^2 at 331 K.
