Evaluation of ceramic materials developed to immobilize ICPP zirconia calcine

Technical Report ·
OSTI ID:6057511
; ;
Various ceramic materials as well as Formula 127 glass has been developed to immobilize ICPP zirconia calcine. Tailored, titanate and matrix encapsulated ceramics were prepared by cold pressing and sintering reactants, while a glass-ceramic was prepared by melting reactants in a manner similar to that for preparing glass. The aqueous leachability, practical loading capacity, and the adaptability to calcine compositional change of the ceramics were investigated and compared to those of Formula 127 glass through application of Soxhlet and MCC-1 Leach Tests. X-ray diffraction techniques were used to determine the presence of radionuclide and calcine matrix element host phases in each ceramic material. Potential process complexity to produce each material was evaluated based on the number of steps required for laboratory-scale preparation. 10 figures, 9 tables.
