4	Etude des conditions de confinement du plomb et du cadmium dans des verres à base de métaphosphates de zinc El Hadrami, Abdelouahab 26 June 2003 (has links) (PDF) Dans le cadre du confinement des métaux lourds toxiques à savoir Pb et Cd, cette étude a porté sur la recherche de nouveaux verres phosphates présentant des propriétés physico-chimiques optimisées. Des verres de composition (100-x) (50P2O5-15ZnO-35PbO)-xFe2O3 et (100-z) [50P2O5-15ZnO-(35-y)PbO-yCdO]-zAl2O3 ont été élaborés. L'introduction des oxydes de fer et d'aluminium dans les matrices phosphatées entraîne une amélioration des propriétés et en particulier un renforcement de la durabilité chimique, en milieu aqueux, comparable à celle des verres silicates. Ces résultats ont pu être corrélés à la formation d'un réseau mixte fortement réticulé dans lequel les cations présentant une coordinence multiple forment des liaisons covalentes à caractère élevé avec les atomes d'oxygène. Avec une température de transition vitreuse modérée, ces verres sont des candidats potentiels pour le stockage d'éléments lourds toxiques.
