Conductivity studies in SnO�?�NaPO3 glasses

[摘要] Na⁺ ion conductivity has been studied in SnO.NaPO₃ glasses, which have been prepared over a wide range of compositions using a microwave melting technique. D.c. activation barriers seem to reflect the structural changes in system. A.c. conductivity analysis has revealed that while the power law exponent, ð‘�?, seem to bear correlation to the structural changes, the exponent ð›�? of the stretched exponential function describing the dielectric relaxation is largely insensitive to the structure. Possible importance of the correlation of transport property to the variation of available non-bridging oxygen (NBO) atoms in the structure is discussed.
