Title
(EN) COLD PROCESSES FOR PREPARING GLASS THROUGH THE USE OF A CRYSTALLINE SILICATE MATRIX
(FR) PROCEDES A FROID DE PREPARATION DU VERRE AU MOYEN D'UNE MATRICE DE SILICATE CRISTALLIN
Abstract
(EN)
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.
(FR)
La présente invention se rapporte à un procédé d'encapsulation de déchets solides se présentant sous des formes appropriées pour être transportés et stockés à long terme, ainsi qu'à un procédé de manipulation des matières toxiques ou radioactives rejetées par inadvertance ou accidentellement. L'invention se rapporte également à la vitrification des déchets toxiques et radioactifs à l'état solide stable, résistant à l'eau, s'effectuant à l'aide d'un procédé qui n'oblige pas à soumettre les déchets à des conditions dures, telles qu'à des pressions et températures élevées ou à une augmentation sévère soit en volume, soit en poids. De nouveaux matériaux sur la base de cette composition de silicate sont également décrits.
