Relations Between Structure and Ionic Conductivity of Some Cristobalite-Related Compounds
Published online by Cambridge University Press: 21 February 2011
Abstract
A comparative study of the isotypic Na2BeSiO4, Na1.8[Ga0.2Zn0.8]SiO4 and Na1.8[Ga0.2Zn0.8]Ge04 structures has revealed differences in conduction pathway geometries, and calculations show that the two Na-deficient compounds possess larger “bottlenecks”. A conduction mechanism, with Na ions using interstitial sites during migration is suggested.
