Abstract
Knowing the redox state of polyvalent elements in glass is important for understanding and controlling the glass properties. In this work we demonstrate the applicability of X-ray photoelectron spectroscopy (XPS) in the determination of the iron redox state in a multicomponent glass having a basalt-like composition. The XPS measurements reveal an entropy-driven reduction of ferric iron to ferrous iron upon increasing melt temperature. Furthermore, the local ferric iron enriched domains, i.e., a kind of inhomogeneity in the glass, is identified by means of XPS. It is proved that XPS is a useful and reliable tool for probing both the average redox state and inhomogeneities in glassy materials.
