dc.description.abstractGd2TiO5 has been identified as a potentially useful material for nuclear based applications such as burnable poison or constituent in waste-forms. A polycrystalline, single phase sample of Gd2TiO5 has been fabricated via the oxide-route reaction. The single phase status and chemical stoichiometry were confirmed using SEM backscattered images, EDS, and laboratory XRD. The structure was confirmed to be orthorhombic, Pnma, space group number 62. The suitability of use for this material in a radioactive environment was tested by in-situ measurement of the materials resistance to transformation from the crystalline to amorphous state via 1MeV Kr2+ ion-irradiation. The in-situ ion-irradiation was carried out using the intermediate voltage electron microscope (IVEM)-Tandem facility at Argonne National Laboratory. The critical dose, Dc, required to render the Gd2TiO5 completely amorphous was determined and the result is compared with other similarly tested materials. Further bulk gold ion-irradiation at various accelerating energies was carried out at the Australian National University using the TANDEM accelerator with damage penetration depth characterised using cross-sectional TEM.en_AU
