Abstract
The structures of four Ni-doped sodium metaphosphate glasses (NiO)x(NaPO3)1âx [x = 0.009, 0.018, 0.033 and 0.074] were investigated by high-energy synchrotron X-ray diffraction (E = 120.0 keV). With increasing NiO content the development of the first nickel-oxygen correlation could clearly be observed in the corresponding pair correlation functions. The high-resolution X-ray diffraction data enabled the separation of the first Ni-O, Na-O and O-O correlations for a-(NiO)0.074(NaPO3)0.926. The first average Ni-O distance is 2.02(2) Ã
and the coordination of Ni with O, which was also determined by EXAFS at the Ni K-absorption edge, is 6. Interatomic distances between phosphorus and bridging (P-OB) or non-bridging oxygen (P-OT) could be discriminated in the structures of all investigated samples.
