Abstract
A study of fixation of caesium on crystalline titania by co-precipitation was carried out. A maximum loading of ∼46wt% of caesium was found to be incorporated in the titania matrix. High leach-resistivity of Cs cations was observed to be in the order of 10−6–10−8 g.m−2.d−1 by Soxhlet flow refluxing at 97 °C of the composite material calcined at 800, 1000 °C for 48 hours. The analysis of X-ray powder diffractions of the composite materials revealed that cesium was fixed in the crystal lattice of host titania with the formation of new mineral phases of CsTi4O9 and Cs2Ti5O11. The results, taken together, implicate that a better fixation of caesium on titania can be achieved by calcination at 1000 °C for 48 hours.
