Abstract Mössbauer and ESR measurements were performed on vanadium borophosphate glasses containing iron. The glass composition was 78 mole% V2O5, 15 mole% P2O5, 7 mole% B2O3 and different amounts of Fe2O3 (0.5–50 mole%) were added. The relative percentage of iron in different states and site positions could be determined for each glass composition. Correlation between the behaviour of iron and its variation in structural units and other physical properties are proposed. A maximum amount of 33 mole% Fe2O3 could be incorporated in the glass network, higher concentrations lead to the precipitation of α-Fe2O3.
