Abstract
The environment around Sr in silicate and aluminosilicate glass has been st udied by neutron and anomalous x-ray diffraction and reverse Monte Carlo mo deling. The first Sr-O distances are smaller in the silicate glass than in the aluminosilicate glass, which can be related to the different structural role of the element in the glass structure. We found Sr-Sr distances at ab out 4 and 7 Angstrom in both glasses, which implies a nonhomogeneous spatia l distribution.
