“…Presumably, these changes reflect thermally activated relaxation of metastable transport properties introduced by the nonequilibrium MA processing. 30,31 The small uncertainties in p and l in Table I are the standard deviations resulting from measuring three samples prepared using the same process. These small standard deviations indicate that the process results in reproducible electronic transport properties despite the use of 99.9% instead of ‡99.999% pure starting materials.…”

A mechanical alloying (MA) process to transform elemental powders into solid Pb 0.5 Sn 0.5 Te with thermoelectric functionality comparable to melt-alloyed material is described. The room-temperature doping level and mobility as well as temperature-dependent electrical conductivity, Seebeck coefficient, and thermal conductivity are reported. Estimated values of lattice thermal conductivity (0.7 W m À1 K À1 ) are lower than some reports of functional meltalloyed PbSnTe-based material, providing evidence that MA can engender the combination of properties resulting in highly functional thermoelectric material. Though doping level and Sn composition have not been optimized, this material exhibits a ZT value >0.5 at 550 K.

“…The effect of thermal treatment had been tested by many researchers [15][16][17][18][19][20]. For instance, Unuma et al [18] measured the Seebeck coefficient and electrical conductivity in a temperature range from room temperature to 600 K in argon atmosphere for pressureless-sintered PbSe ceramics.…”
