Abstract

Various ceramic materials as well as Formula 127 glass have been developed to immobilize ICPP zirconia calcine. Tailored, titanate and matrix encapsulated ceramics were prepared by cold pressing and sintering reactants, while glass-ceramics were prepared by melting in a manner similar to that of preparing the glass. X-ray diffraction techniques were used to determine the presence of radionuclide and calcine matrix element host phases in each ceramic material. The aqueous leachability, practical loading capacity and the incorporation of waste elements into host phases was investigated and compared to those of Formula 127 glass through application of the Soxhlet and MCC-1 static leach tests. Potential process requirements for each material were evaluated based on the number of steps needed for laboratory-scale preparation.
