PbTe-PbS materials are promising for thermoelectric power generation applications. For the composition of (Pb 0.95Sn 0.05Te) 0.92(PbS) 0.08 nanostructuring from nucleation and growth and spinodal decomposition has been reported along with thermal conductivity of approximately 1.1 W/m·K at 650 K . Based on temperature-dependent measurements of electrical conductivity, thermopower, and thermal conductivity, the thermoelectric figure of merit, ZT, are ∼1.5 at 650 K for cast ingots. To develop larger quantities of material for device fabrication, advancement in the synthesis, processing and production of (Pb 0.95Sn 0.05Te) 0.92(PbS) 0.08 is necessary. Powder processing of samples is a well-known technique for increasing sample strength, and uniformity. In this presentation, we show sample fabrication and processing details of pulsed electric current sintering (PECS) processed (Pb 0.95Sn 0.05Te) 0.92(PbS) 0.08 materials and their thermoelectric properties along with the latest advancements in the preparation of these materials.
