Abstract

The paper discusses the relevance of a number of structural and microstructural characteristics for the evaluation of the physico-chemical stability of iron-silicate glasses developed for conditioning radioactive waste. Mössbauer spectroscopy is used to obtain information about the valency state and coordination of iron in the glass, whereas the study of devitrification kinetics and products allows one to conclude that for this type of material devitrification will not be a determining factor in the safety evaluation of any final disposal option.
