    Abstract
  • In this paper, lead telluride was successfully synthesized by a high-pressure and high-temperature (HPHT) method. XRD results show that the samples are polycrystalline with rock salt structure. The orientation of PbTe samples is varying with the increasing synthesis pressure. Scanning electric microscope (SEM) results show that the synthesized PbTe samples possess high orientation. The electrical resistivities of PbTe samples are about 1～2 magnitudes lower than those of the samples sintered at ambient pressure, and decrease with the increase of the synthesis pressure. The thermal conductivities of the PbTe samples synthesized by HPHT are lower than those of the samples fabricated at ambient pressure. These results indicate that thermoelectric properties of PbTe samples can be improved by high-pressure and high-temperature approach.
