After Kyoto (1983), Honolulu (1985), Paris (1991), Honolulu (1993) and Dresden (1997) then MS6 continues a series of International Conference on Molten Salt Chemistry & Technology. Like all preceding symposia the scope of MS6 in Shanghai remains, as usual, the scientific and technology exchanges of progress in molten salt chemistry & technology. Bridging the gap between fundamentals and technical application will be a major issue of the conference.
        The conference consists of 5 plenary lectures, 26 keynotes, 30 short oral presentations and about 45 posters. In order to minimize parallel sessions and due to the limited time, we had to only accept a part of contributions as oral presentations. Therefore, the posters provide excellent contributions for the conference.
        The local organizers would like to thank the international scientific board and the Japanese molten salt committee for their supports, both scientific and financial. Also, the organizers acknowledge gratefully the financial support by National Natural Science Foundation of China. At last, we would like to be most grateful to Shanghai University, which helped us in organizing the conference. Now we look forward to a successful and enjoyable conference in Shanghai.
