Composition And Properties Of Glass Ceramics Produced From Incinerator Residuals

Vitrification of waste materials is a method that is well established as a means to immobilize inorganic constituents in the waste. Vitrification has been extensively applied in remediation of nuclear wastes by engineering the glass composition to serve as a host to the radionuclides, and to achieve maximum resistance to solution by leaching media. Vitrification of non-nuclear, hazardous wastes has been extensively researched and applied in a few remediation projects/processes. These efforts with hazardous wastes have involved forming a glass followed by casting billets or by slag granulation processes. Previously, formation of glass ceramics, ie substantially crystaline products, in waste remediation efforts had not been reported.
