摘要
Neutron scattering measurements with isotopic substitution of Ti have been carried out on a K2O-TiO2-2SiO(2) glass using Ti-46 and Ti-48 isotopes. The total structure factors and the first difference function (giving all the partial pair correlation functions centred on Ti) were fitted by the reverse Monte Carlo (RMC) technique to generate a three-dimensional structural model of this glass. Information was obtained on the medium-range ordering around Ti. The structure determined with RMC indicates a non-homogeneous distribution of Ti in the glass in agreement with the available scattering data.
