High-temperature XAFS measurement of molten salt systems

Okamoto, Yoshihiro ; Akabori, Mitsuo; Motohashi, Haruhiko*; Ito, Akinori; Ogawa, Toru

Measurement system for the high temperature XAFS was developed for investigating the local structure of hygroscopic molten salts like rare earth halides. Solid sample was enclosed in the upper tank of the quartz cell having a sandglass shape under reduced pressure to avoid oxygen and moisture. The measurement was carried out at the electric furnace of the highest arrival temperature 1273K. After melting, the sample runs down through the melt path with 0.1mm(or 0.2mm) thickness to the lower tank. The minimum energy which could be measured was about 10keV mainly due to the absorption of the quartz. It was confirmed that the measurement of the expensive hygroscopic sample became possible in the present work.
