Waste form development for pyrometallurgical processing

Description
Pyrometallurgical process generates chloride waste salt, which is very soluble in water and hard to be directly vitrified. We, CRIEPI, has been developing two methods to immobilize the waste in parallel; one is vitrification using electrolysis of chloride to metal followed by oxidation, the other is dry synthesis of sodalite-type waste form. Electrolysis and oxidation experiments showed the feasibility of the vitrification processes. As for sodalite, synthesized sodalite by heating at 1073K for 100 to 200 hours was found to have higher leach-resistance than conventional vitrified waste form. (author)
