The many kinds of experimental techniques, such as, the long capillary method and the shear cell method, have been devised in the ground base research for the measurement of diffusion coefficient in such high temperature melts. Recently, the shear cell technique coupled with the microgravity condition was applied to the measurements of high temperature metallic melts. This technique enables us to measure the diffusion coefficient with high precision. In this paper, a brief discussion is given for the trends of previous diffusion experiments in space performed by Japanese researchers. Recently, Japanese space agency, JAXA, is developing the shear cell technique for the future space experiments in JEM. The current status of the development of our shear cell technique is summarized and new results are presented for typical experiments on the ground by using test samples, for example, liquid silver-gold alloys., 資料番号: AA0049301002, レポート番号: JAXA-RR-05-034E}, title = {Current status of the development of shear cell technique in ground base research and towards JEM on ISS}, year = {2006} }
