Modification of thermoelectric properties in Ca3Co4Oy ceramics by Nd doping

Ca3-xNdxCo4Oy polycrystalline thermoelectric ceramics with small amounts of Nd have been synthesized by the classical solid state method. X-ray diffraction data have shown that all the Nd has been incorporated into the Ca3Co4O9 and Ca3Co2O6 phases and no Nd-containing secondary phases have been prod...
