dc.description.abstractGarnets, A3B2C3O12, are considered to be potential host phases for the immobilization of high-level nuclear waste as they can accommodate a number of elements of interest, including Zr, Ti and Fe. The naturally occurring garnet, kimzeyite, Ca3(ZrTi)2(SiAlFe)O12, can contain ∼30wt% Zr. An understanding of the radiation tolerance of these materials is crucial to their potential use in nuclear waste immobilization. In this study two synthetic analogues of kimzeyite of composition Ca3(ZrTi)2(SiAlFe)O12 and Ca3Hf2FeAlSiO12 were monitored in situ during irradiation with 1.0 MeV Kr ions using the intermediate voltage electron microscope-tandem user facility (IVEM) at Argonne National Laboratory. The structure of these materials was previously determined by neutron diffraction and 57Fe Mössbauer spectroscopy. Ca3(ZrTi)2(SiAlFe)O12 and Ca3Hf2FeAlSiO12 have very similar structural properties with cubic la3d symmetry, the only significant difference being the presence of Zr and Hf, respectively on the 6 coordinated B sites. © 2009 AINSEen_AU
