Abstract

High resolution X-ray diffraction (XRD), neutron diffraction (ND) and reverse Monte Carlo (RMC) modelling of a rapidly quenched multi-component oxide glass reveals a local atomic order largely made up by interactions between Si, Fe and Mg polyhedra, the stereochemistry of which is in close agreement with literature data. Overall, the glass was found to consist of a small number of basic Si-O, Fe-O and Mg-O clusters. A superposition of the ND dataset promotes an RMC supercell with a higher fraction of uncoordinated oxygens, more pronounced Fe-Al cluster interconnections and a markedly reduced Fe-Si-Mg cluster bridging, as compared to the RMC-generated environment restricted solely by XRD total scattering.
