Abstract
A process leading to titanate-based crystalline ceramic waste forms for commercial high-level nuclear waste is described. Precursor materials referred to as hydrous calcium titanates are prepared by sol-gel-related techniques. Radionuclides are retained on the precursors by ion-exchange/sorption reactions and the material is converted to a dense, ceramic form by hot-pressing. Transmission electron microscopy-electron microprobe characterization was used to determine the effects of compositional changes and process variations on microstructure.
