| Popis: | The ac electrical measurements have been just reported for alkali halide mixed crystals that were melt grown from NaCl, KCl and KBr starting materials. They showed a nonlinear variation of all the electrical parameters with the bulk composition. In this short paper, we show that these mixed systems, depending on their major constituent, are classified into three categories in each of which, the activation energy for the ac conductivity increases linearly with BΩ, where B is the isothermal bulk modulus and Ω the mean volume per atom. In addition, the resulting three straight lines are formed to have almost the same slope. © 2009 Elsevier B.V. All rights reserved. |
