The Structure of Alkali Tellurite Glasses

摘要: Structural models of alkali tellurite glasses, (M2O)x(TeO2)l-x with M = Li, Na, K are presented. The glass structure was studied neutron and X-ray diffraction, and, in the case sodium, NMR. Real-space were built using reverse Monte Carlo algorithm. distribution polyhedral types as a function alkaline ion type composition is derived. It concluded that broad species, compared to found crystalline tellurites similar composition, responsible for marked resistance devitrification shown by these glasses.
