Abstract: High-pressure X-ray diffraction study by using synchrotron radiation source was carried out to determine the synthetic condition of high-pressure synthesis. We also open our cell assembly of multi anvil apparatus which is readily available for beginners of high-pressure experiment. The synthetic condition of Mg2Si, which is expected to be inexpensive thermoelectric material, was explored by means of X-ray diffraction study. High-pressure synthesis of Mg2Si was performed by piston cylinder equipment. Thermoelectric properties of Mg2Si including Seebeck coefficient and electrical conductivity were measured at room pressure and high temperatures. A simple measurement system we develop enables us to measure the thermoelectric properties of small-sized synthesized sample under pressure.
