Heat of mixing of equiatomic alkali-alkali alloys
Journal of Physics F: Metal Physics, 1980The Gibbs-Bogoliubov variational technique is used to study the internal energy and entropy of liquid alkali metals as well as heat of mixing and excess entropy of mixing for equiatomic NaK, KRb and NaCs alloys. A Heine-Abarenkov-type model potential has been considered with Hartree, Hubbard-Sham and Vashishta-Singwi exchange and correlation functions.

Alkali ionic transport in mixed alkali glasses
Journal of Non-Crystalline Solids, 1993Abstract The diffusion coefficient of an alkali ion in oxide glass, as well as dc conductivity, decreases drastically when a second alkali ion is introduced. This reduction in ionic transport rate is attributed to an increase in the activation energy. An expression is derived for the composition dependence of the activation energy for ionic transport
