In this article, the experimental technique of synthesizing skutterudite compounds using multi-anvil-type high-pressure apparatus is described in detail. We also present the experimental technique of in situ observation for crystallization of the compounds under high temperatures and high pressures using synchrotron radiation. Using the technique for in situ X-ray diffraction, we determined the crystallization condition of some binary skutterudite compounds and filled skutterudite compounds under high pressure.
