However, the formation mechanism of clathrate structure has not yet been clarified due to lack of study and understanding of their liquid state structure and properties. Therefore, in order to clarify the formation mechanism of the clathrate structure, thermophysical properties (density, surface tension, and viscosity) of BaGe alloys melts around their eutectic compositions were measured by using the electrostatic levitation (ESL) technique and also the structure of them was observed by using the high-energy X-ray diffraction method combined with the ESL. We found that from experimental results, the short range order based on the clathrate structure would exist even in the liquid state at the clathrate forming compositions., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113046}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {静電浮遊法を用いた Ba-Ge 融体の構造と熱物性測定}, volume = {22}, year = {2006} }
