Abstract
The structure of 5SiO(2) . 2Ta(2)O(5) . 3Na(2)O glass has been investi gated by X-ray radial distribution analysis based on X-ray diffraction intensity measurements. The electron radial distribution function was calculated by the usual Fourier transformation and interpretation of it was made in terms of pair functions. It has been found from the det ermined peak positions and pair function analysis that most of the Ta5 + ions are present in six-fold coordination form. It was deduced that the TaO6 octahedra are distorted in the glass structure.
