Abstract

THE ACCEPTANCE FOR PRACTICAL IMPLEMENTATION OF THE CONVERSION OF SPENT INORGANIC MATERIAL TO WASTE CERAMICS IS HAMPERED BECAUSE OF THE COMPLEXITY OF THE RELATED FABRICATION TECHNOLOGY. THE WORK DESCRIBED HERE SHOWS THE POSSIBILITY OF IMPROVING THIS SITUATION BY RESORTING TO SOL GEL TECHNIQUES. SUPERIOR QUALITY ION EXCHANGE XEROGEL TITANATES IN THE FORM OF MECHANICALLY RESISTANT, SIZE CONTROLLED MICROSPHERES CAN BE PREPARED USING A SIMPLE SOL-GEL TECHNIQUE. THE TITANATE PARTICLES CAN BE ALSO USED AS PRECURSORS IN EVAPORATIVE DEPOSITION ON XEROGEL PARTICLES (EDXP) A NEW WASTE SOLIDIFICATION PROCESS BASED ON PHYSICAL IMPREGNATION OF THE SEROGEL MATERIAL WITH THE WASTE LIQUID FOLLOWED BY EVAPORATION. WASTE LOADED ION EXCHANGE MICROSPHERES CAN BE CONVERTED TO LEACH RESISTANT CERAMICS BY FIRING AND/OR COLD PRESSING AND SINTERING AT 900 C-1100 C. SOL-GEL INORGANIC ION EXCHANGE AND EDXP MAY FIND USEFUL APPLICATION IN CONDITIONING OF VARIOUS TYPES OF MAW STREAMS.
