Radiophase Development in Hot-Pressed Alkoxide-Derived Titanate Ceramics for Nuclear Waste Stabilization

Phase development as a function of hot‐pressing temperature was studied in alkoxide‐derived titanate‐based ceramics doped with a 10 wt% loading of a sodium‐rich (NAR) and a sodiumpoor (NAP) simulated high‐level waste. Pyrochlore was found to be the most abundant phase in both calcine powders. A pseu...
