Abstract

Boro-phosphate oxide glass system doped with iron ions have been prepared by the conventional melting quenching technique, all mixtures are in an agreement with the following chemical formula (25-x) mol% Na2O. x mol% NaCl.15 mol% FeO. 30 mol% B2O3. 30 mole% P2O5, where x = 0.0, 05, 10, 15, 20 and 25. Sample of x= 0, only, has been exposed to different doses of gamma rays (0.0, 05, 10 and 20 kGy). Mossbauer Effect ME spectroscopy have been carried out at RT for all irradiated {x =0.0} and for non-irradiated {x> 0.0} samples. ME parameters showed all samples in good glassy state. Also ME parameters showed the iron ions in two different coordination states, where all Fe2+ ions and some of Fe3+ ions shared the octahedral coordination states, while the tetrahedral coordination states occupied only by Fe3+ ions. It was observed that both the gamma irradiation process and the process of replacement Na2O by NaCl caused the Fe2+ ions to oxidize to Fe3+ ions.
