Chemical states of cesium in clay minerals heat-treated at a high temperature and in refractory material which was immersed in molten slag were investigated by X-ray absorption fine structure (XAFS) analysis. Although the coordination structure of adsorbed cesium was different between illite and vermiculite, it became the similar structure at the high temperature each other. The chemical state of cesium accumulated in the brick was clearly different from that in slag. The EXAFS function obtained from the brick was almost the same as that of the molten clay minerals containing cesium.
