| Abstract Scope |
The crystal growth of uranium and transuranium containing phases has been accomplished via two different crystal growth routes, mild hydrothermal and high temperature solution flux growth. In both cases we are targeting the preparation of new compositions to evaluate their potential use as nuclear waste forms. The mild hydrothermal route works extremely well for crystallizing complex fluoride phases, such as Na3GaU6F30, Na3AlNp6F30, Na3FePu6F30, and Cs2NiNp3F16, while the high temperature flux route works well for crystallizing oxide phases, such as Cs2PuSi6O15 and Na2PuO2(BO3). The synthesis and structures of these phases will be discussed, along with our appraoch of identifying potential compositions that we can pursue synthetically. |
