Annotatsiya
A structural model on tellurite glasses, based on neutron diffraction data, is proposed. The coordination scheme of Te is determined and the binding system of the basic coordination polyhedra is establihsed. The role of the modifier (Fe2O3) in the glasses is discussed. The atomic density radial distribution function obtained, permits to conclude that the interatomic distances in the region 3.7 to 4.0 Å considerably increase at the vitreous state transition.
