摘要：
Niobophosphate glasses (P2O5-PbO-Nb2O5-K2O XFe2O3), were studied using thermally stimulated depolarization currents and Mossbauer spectroscopy in samples of different iron concentrations, and were subjected to oxidation and reduction processes. The use of both techniques provided new information about the distribution of iron and niobium between tetrahedral and octahedral sites.
