  • Process for Converting Alkaline-Earth Metal Chlorides to Tungstates and Molybdates and Applications Thereof
    Publication number: 20100305384
    Abstract: The invention relates to a process for converting an alkaline-earth metal chloride to at least one salt chosen from the tungstates and molybdates of this metal, which comprises the reaction of the alkaline-earth metal chloride with at least one precursor of tungsten or of molybdenum chosen from tungsten oxides, molybdenum oxides, tungstates and molybdates, this reaction being carried out in a solvent constituted by KCl or by an LiCl/KCl mixture and at a temperature at least equal to the melting point of this solvent. Applications: synthesis of alkaline-earth metal tungstates and molybdates, extraction of alkaline-earth metals from media in which they are found in the form of chlorides, recovery of alkaline-earth fission products from a salt flux in the context of the reprocessing of a spent nuclear fuel in molten chloride media, etc.

  • USE OF THE FLASH SINTERING TECHNIQUE FOR THE SYNTHESIS AND DENSIFICATION OF IODOAPATITES
    Publication number: 20100276634
    Abstract: The invention relates to the use of the technique known as “flash sintering” for the synthesis and densification of iodine apatites or iodoapatites. Applications: reprocessing of spent nuclear fuels in order to condition and store, in an apatite, the radioactive iodine present in the aqueous effluents from this reprocessing and, in particular, iodine-129.
