| Popis: | The environment around Sr in silicate and aluminosilicate glass has been studied by neutron and anomalous x-ray diffraction and reverse Monte Carlo modeling. 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 about 4 and 7 \AA{} in both glasses, which implies a nonhomogeneous spatial distribution. |
