La 1-x Sr x CoO 3 (x=0, 0.05) powders were prepared using the citrate-gel (Pechini) process. Pellets formed from these powders were sintered at various temperatures. All samples were characterized by means of X-Ray Diffraction and Scanning Electron Microscopy in order to investigate their structural and morphological properties. The electrical resistivity, thermal conductivity and thermopower were measured in a wide range of temperatures (2-350K) in order to understand the influence of the different processing conditions on the thermoelectric properties of the compounds.

In this work, Na-doped PbTe is synthesized through a low temperature synthesis technique. This method provides highly efficient p-type PbTe using a synthesis temperature much lower than the PbTe melting point and as low as 430 C followed by sintering at 600 C. A maximum ZT of 1.36 at 720 K is achieved for the Pb 0.98 Na 0.02 Te sample arising from a high power factor and a very low lattice thermal conductivity. The low thermal conductivity is attributed to the in situ nanostructuring achieved by the low temperature synthesis method, followed by cold pressing and sintering.
