Abstract

60P₂O₅-40Fe₂O₃ glass was synthesized and ⁵⁷Fe Mössbauer spectroscopy study was presented. The main goal of the research was to investigate structural changes of local environment of iron ions during gradual crystallization of the glass. It was observed that some changes were evidenced at temperature of heat treatment higher than 400°C, above which content of tetrahedrally coordinated Fe₃₊ was increased in cost of octahedral sites. This led to formation of areas of nucleation of α-FePO₄. Crystallization of α-Fe₃(P₂O₇)₂ and Fe₂P₂O₇ was also observed.
