    Abstract
  • La-filled skutterudite compounds LaxCo4Sb12 (0＜x1.0) were successfully synthesized at 3.5 GPa and 900 K. The X-ray diffraction results indicate that all synthesized samples exist as a single phase with a crystal structure of CoSb3. The composition-dependent electric transport properties of La-filled CoSb3 have been studied at room temperature. The lattice parameters of the samples increase gradually with the increasing of La content. No La phase is found in the range of x from 0.1 to 1.0. The La-filled skutterudite is p type semiconductor. The electrical resistivity and Seebeck coefficient increase firstly with the increasing of La content and then decrease. When the La content x is 0.3, the electrical resistivity and Seebeck coefficient both reach the maximum value. The maximum power factor is obtained when the La content x is 0.5.
