摘要：

Glasses in the x Na2O(1-x)TeO2 system have been synthesized for 0.18 less than or equal to x less than or equal to 0.33. Glass transition temperature and density data are reported as a function of x. In the glass forming region, ionic conductivity spreads over two orders of magnitude at 200 degrees C when the total concentration of sodium cations varies only by a factor of two. Conductivity data obey an Arrhenius type behaviour with a same pre exponential term in agreement with an interstitial mechanism for ion transport.
