Abstract
Immobilization of Cs in ceramics based on perovskite and zirconolite by self-propagating high-temperature synthesis (SHS) was studied using model systems. The ceramics was obtained as cylindrical blocks. Cesium can be completely immobilized in ceramics at 1250°C in the form of synthetic mineral pollucite and, in this case, it is uniformly distributed through the bulk of the ceramic sample. The optimal synthetic conditions were determined, and the phase composition of the ceramics was evaluated. The leaching rates of Cs from ceramics in double-distilled water at 20°C were determined.
