Chemically bonded phosphate ceramics (CBCs) were investigated for low-temperature stabilization and solidification of DOE mixed wastes where conventional high-temperature treatments cannot be used due to presence of volatiles and pyrophorics in the wastes. This article deals with stabilization of chemical contaminants. Phosphate ceramics of Mg, Mg-Na and Zr are being investigated as candidate materials. The authors discuss the basic properties of the phosphate waste forms made with surrogates of typical DOE mixed wastes with an emphasis on ash waste stream. The performance of the final waste forms, including leachability of the contaminants durability of the final waste forms in aqueous environment, and strength of the waste forms are discussed in detail. Based on the results, the authors present possible economic applications of these materials.
