Abstract

The present invention discloses a process for solid waste encapsulation in forms suitable for long term storage and transportation as well as a process for handling inadvertent toxic or radioactive releases and accidents. The glassification of toxic and radioactive wastes in a stable, water resistant solid by a process that does not require subjecting the waste to harsh conditions of elevted pressures and temperatures or a drastic increase in either volume or weight is described. Novel materials based on this silicate composition are also disclosed.
