摘要: Abstract As an approach to the mixed alkali effect in glass, self-diffusion coefficients of sodium and cesium ions Na 2 OCs OSiO glasses were measured at temperatures 350–550°C. Electrical conductivity transport number for also measured. The substitution glass by different caused mobility each ion decrease pronouncedly activation energy migration increase rapidly. was attributed alkali-oxygen bond strength resulting from presence two kinds ions. This is related expectation that activity decreases when are mixed.
