Abstract

Short-Range and Medium-Range Order in Lithium Silicate Glasses. Part 1. Diffraction Experiments and Results.-Neutron and X-ray diffraction experiments including isotopic substitution methods enable the description of both short-and medium-range structures of glasses of the composition (Li2O)x(SiO2)100-x (X: 0, 20, 33.3, 40). Atomic pair distances and partial coordination numbers obtained from the pair distribution functions are presented for the short-range structure. In the medium-range region, i.e. for distances ¿ 0.5 nm, the amplitudes of oscillation in the pair-distribution junction increase with increasing Li2O content. -(UHLIG, H.; HOFFMANN, M.
