Production of metal-containing materials from sols

Abstract

Abstract TO A HYDROUS METAL SOL OF THE RELEVANT METAL OR METALS (E.G., URANIUM, ALUMINUM, ZIRCONIUM, IRON, TITANIUM) IS ADDED A NON-CELLULOSIC, NON-DEHYDRATING ORGANIC POLYMER SOLUBLE IN THE HYDROUS SOL AND SELECTED FROM THE GROUP CONSISTING OF POLYHYDROXY, POLYCARBOXYLIC AND POLYAMINE POLYMERS WHICH FORM A COMPLEX WITH SAID HYDROUS METAL OXIDE, SAID ORGANIC POLYMER BEING CAPABLE OF INCREASING THE VISCOSITY OF THE SOL. THE SOL IS FORMED INTO ENTITIES OF A SELECTED PHYSICAL CONFIGURATION, E.G. DROPS, AND THE ENTIRES TREATED WITH AN AGENT CAPABLE OF PRECIPITATING THE METAL OXIDE, E.G., A BASE SUCH AS AMMONIA, TO CONVERT THEM TO A GEL, E.G., OF DISCRETE SPHERES, CONTAINING THE METAL. THE ORGANIC COMPOUND CAN BE DRIVEN OFF BY HEATING.
