- Abstract
- The bond valence method is applied to analyze local structure models from reverse Monte Carlo (RMC) fits to diffraction data. While our earlier studies demonstrated that for a wide range of silver ion conducting glasses both absolute value and activation energy of the ionic conductivity may be predicted from the volume fraction of regions with a sufficiently low valence mismatch for the silver ion, this investigation focuses on the precautions that have to be considered in a generalization of the bond valence approach to ionic conductors with various types of mobile ions and especially to alkali-metal ion conducting glasses. The separate structure conductivity correlations observed for each mobile cation can be combined to a unified empirical relationship by employing the square root of the cation mass as a scaling factor.
