The immobilization of Cs has been studied by the calcination of the Cs-form of various kinds of mordenites. In this study, the effect of various parameters such as calcining temperature and time, components in mordenites, conditions for cold and hot pressing, on the immobilization of Cs in ceramic products are evaluated by using X-ray diffractometry (XRD), density balance (Archimedes' method), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). Results showed that recrystallization to the stable ceramic solid forms of CsAlSi

was achieved only in calcination of Synthetic Mordenite-C which contains Ti and Fe as binder. The Cs-form mordenites were pelletized into a disk by cold isostatic pressing and the density of the solid forms increased with calcining temperature and time.

Immobilization of cesium separated from high-level liquid waste was studied by using a mordenite, which adsorbs cesium selectively. Ceramic samples were prepared by pressing and sintering the mordenite loaded with cesium. Ceramics of the higher density were obtained by sintering the pressed mordenites of the smaller particle size. The density of the sample sintered with pressing, which is called hot-pressing, was higher than that of the sample sintered after pressing by a facor of 1.5.
