Abstract
The environment around Li in a LiAlSiO4 glass has been studied by neut ron scattering with isotopic substitution of Li and reverse Monte Carl o modeling. Li atoms are found in distorted tetrahedral sites which ar e edge-linked with (Si,Al)O-4 tetrahedra and with a first Li-Li distan ce near 5 Angstrom. The increase in the activation energy for ionic co nduction from the aluminosilicate to the silicate glasses is explained by the structural differences.
