In-situ observation of crystallization of TSb₃ (T=Co, Rh and Ir) under high temperatures and high pressures

Synthesizing processes of the binary antimony-based skutterudite compounds, CoSb₃, RhSb₃ and IrSb₃ 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 synthesis condition of these compounds under high pressure.
