Study on the High Temperature Stability of YbyCo4Sb12/Yb2O3 Composite Thermoelctric Material

doi:10.3724/SP.J.1077.2014.13261

Abstract

Abstract: Yb_yCo₄Sb₁₂/Yb₂O₃ filled skutterudite composite with nominal compositions of y=0.6 was synthesized, in which the Yb₂O₃ particles in nanometer and/or micrometer sizes dispersed mainly on the grain boundary. The high temperature stability of the composite was investigated. It was found that the thermoelectric properties (electrical conductivity, Seebeck coefficient and thermal conductivity) and the microstructure features (grain size, amount and dispersion of oxide particles) , Yb filling fractions were almost unchanged after heat treatment at 873 K for 30 d, resulting in almost unchanged maximum ZT values of about 1.2. A large number of dislocations were observed in the grain interior. The stress generated by dislocations is considered the major factor to effectively prevent the “escape” of Yb ions from the Sb-cages and to block the migration of the Yb²⁺ ions and O₂- ions, thus preventing the generation of oxide particles.
