5–15 mol % UO₃ loaded zinc iron phosphate glass was prepared by melt quench process. The solubility of UO₃ in ZnIP was determined by XRD and was found to be below 15 mol %; beyond which separation of UP₂O₇ com¬pound was observed. Mössbauer spectroscopy unraveled the ratio of Fe (II)/Fe(III) and was found to decrease from 0.071 (ZnIP) to 0.029. EXAFS studies unraveled the prevalence of two type of coordination for U–O (i.e U–O₁ and UO₂) and Fe–O (Fe–O₁ and Fe–O₂) in the ZnIP glass matrix, whereas a single chemical environment for Zn–O in the same glass matrix.
