Abstract:
A series of OH--free NaF single crystals has been prepared and the influence of substitutional calcium ions on the ionic conductivity has been studied. The activation energy for migration of a cation vacancy in NaFCa is 1.36 plus or minus 0.1 eV. An isothermal plot of ionic conductivity vs. divalent impurity concentration has been used to analyze several nominally pure NaF samples for divalent impurity levels. Author
