Abstract: The use of D2O rather than H2O for leaching Synroc and its constituent phases allows the study of hydration and hydroxylation reactions without the contaminating influence of atmospheric moisture. For Synroc leached at 190 deg C for 5-30 days, the penetration of D into the Synroc is found as ∼30 nm from both energy recoil analysis using 1.5 MeV He ions from a Van de Graaff accelerator and secondary ion mass spectroscopy near mass 18(OD-). Analogous studies have been carried out on single crystals of SrTiO3 which have the perovskite (a constituent phase of Synroc) structure, and augmented by additional atomic force and scanning electron microscope studies of secondary TiO2 alteration products. Alteration products on single crystals of CaTiO3 have also been studied.
