Synthesis and Analyses of Thermoelectric Lead Telluride

Year: 2013

Type: article

Abstract: The influence of chemical composition effects, modes of synthesis, pressing on the structural states and electrical qualities of lead telluride has been investigated. The analyses indicated that thermoelectric parameters of the investigated materials depend on technological factors. The results revealed that conductivity is n-type in stoichiometric composition equilibrium and lead-excess states, while conductivity is p-type in tellurium-excess states. The maximum value of the Seebeck coefficient, which characterizes the thermoelectric materials, was obtained at d = 0.8-1.0 mm for powder fractions and 0.75-1.0 GPa for pressed.
