Incorporation of Radioactive Ashes into Ceramic-Clay Matrices Available to Purchase

The possibility for immobilization of ashes arising from incineration of radioactive wastes generated in research centers was investigated on a laboratory scale. Ceramic materials based on natural clays were made by routine ceramic techniques. It was shown that ceramics on the basis of Chasovyar clay may incorporate up to 30 vol% of ash and that the products obtained at 1050°C have a high chemical stability and mechanical strength. It is concluded that the proposed method deserves further study aimed at the development of process equipment.
