Solid State Cells with Buffer Electrodes for Measurement of Chemical Potentials and Gibbs Energies of Formation: System Ca-Rh-O

When the alkoxide precursor to Synroc is heated to 800°C in air, a cubic oxide is formed. This phase is shown by X-ray and neutron powder diffraction to have the fluorite (a=4.99 ?) rather than the pyrochlore structure. This has important implications for waste encapsulation
