Structure And Properties Of 137Cs Containing Waste Glass

Vitrification has been recognised as the best method of neutralisation and immobilisation of the radioactive and toxic wastes. Toxic elements are introduced into the structure of chemically durable glasses (waste glasses). Radioactive 137Cs is a dangerous containment of hospital and laboratory wastes. Incineration of these waste followed by vitrification of the ashes by co-melting them with borosilicate glass is a prospective method of immobilisation of 137Cs for safety waste storage. The influence of partial substitution of Na by Cs and introduction of CaO as the main component of hospital waste incineration ash on the structure, crystallisation ability and the physical properties of SiO2-B2O3 -Al2O3-Na2O glass was studied.
