【 摘 要 】

The antimony-based partially-filled skutterudite compound MmxCo4Sb12 (Mm=mischmetal) are expected for n-type thermoelectric materials with high-perfomance and low-cost. In order to prepare high-quality samples of the compound, synthesizing processes at high pressures and high temperatures have been studied by means of in-situ x-ray diffraction measurements using synchrotron radiation and a cubic-anvil high pressure apparatus. In series of the experiments, we could obtain the optimum condition for synthesizing the compound under high pressure.
