Novel chemically bonded phosphate ceramics have been investigated for stabilization and solidification of chloride and nitrate salt wastes. Using low-temperature processing, we stabilized and solidified chloride and nitrate surrogate salts (with hazardous metals) in magnesium potassium phosphate ceramics up to waste loadings of 70-80 wt.%. A variety of characterizations, including strength, microstructure, and leaching, were then conducted on the waste forms. Leaching tests show that all heavy metals in the leachant are well below the EPAs universal treatment standard limits. Long-term leaching tests, per ANS 16. 1 procedure, yields leachability index for nitrate ions> 12. Chloride ions are expected to have an even higher (i.e., better) leachability index. Structural performance of these final waste forms, as indicated by compression strength and durability in aqueous environments, satisfies the regulatory criteria. Thus, based on the results of this study, it seems that phosphate ceramics are viable option for containment of salt wastes.

The first chemically bonded phosphate ceramics (zinc phosphate dental cements) were developed over a century ago. However it has only been in the last 30 years that a new breed of materials has been discovered. This book brings together latest developments in this field including several novel ceramics, from Argonne and Brookhaven National Laboratories. Coupled with further advances in their use as biomaterials, these materials have found uses in diverse fields in recent years. Applications range from advanced structural materials to oil-well cements and stabilization and encapsulation of hazardous and radioactive waste. Such developments call a single source for their science and applications. This book provides the first comprehensive account to fulfil this need. · Providing a foundation into the latest developments in chemically bonded phosphate ceramics. · Explores new CBPC's with a wide range of practical applications. · Over 30 years worth of developments and applications in the field available in a single source
