A hydroceramic waste form is designed specifically to solidify and isolate sodium bearing waste (SBW) in storage at various U.S. Department of Energy (DOE) sites. The acidic waste produced during reprocessing of fuel rods was over-neutralized with sodium hydroxide (NaOH) and stored in underground tanks at DOEs Hanford and Savannah River sites. Concentrations of NaOH in the SBW can range from 4 to 12 M. Additionally,some of the SBW is nearly pure NaOH whereas others can contain large amounts of sodium salts. A hydroceramic is a monolithic solid consisting of tectosilicates (zeolites, feldspathoids) that can be made from metakaolin and concentrated NaOH. The starting materials are mixed together forming a thick paste, precured at room tempera...
