A review of Miissbauer data on inorganic glasses: the effects of composition on iron valency and coordination

Over the last twenty years, the technique of stFe Mdssbauer spectroscopy has been widely used to characterize the structural role of iron in a broad range of glass compositions. This overview of previous work on iron-bearing glasses covers both geological and ceramic re-search on Fe-bearing Na-Si-O, borate, phosphate, and more complex silicate systems. Mdssbauer work on multi-component synthetic compositions is reviewed in terms of the effects ofeach separate cation on Fet * lFe2 * ratios and iron site occupancies
