摘要：

A Fe-57 Mossbauer spectroscopy study is presented. The main goal of the research was to investigate the structural information of the glass-like the coordination numbers and redox ratio of the iron. Most of the iron, about 80%, is present in the glass as Fe3+, which is composed of tetrahedral (57%) and octahedral (23%) coordinated iron. The rest of the iron, about 20%, is in the oxidation state Fe2+. This iron could be mostly present as Fe-VI(2+), but five-fold coordinated iron is also possible. Finally, the structural model of the synthesized 60P(2)O(5)-40Fe(2)O(3) glass was proposed.
