Environment of titanium and aluminum in a magnesium alumino-silicate glass [PDF]

Journal of Physics: Condensed Matter, 2009
The structure of the glass 2MgO-2Al(2)O(3)-5SiO(2)-TiO(2) was investigated using neutron diffraction with isotopic substitution. Reverse Monte Carlo (RMC) modeling was used to reproduce experimental structure factors derived from diffraction experiments.
