Title: Silver diffusion and ionic conduction in Ag/sub 6/I/sub 4/WO/sub 4/ solid electrolyte

This paper studies the diffusion of silver (Ag/sup 110m/) and the Haven ratio found for the first time at temperatures between 110 and 190/sup 0/C. A mixture of the salts AgI and Ag/sub 2/WO/sub 4/ (molar ratio) was obtained by joint precipitation with silver nitrate from solutions containing stoichiometric amounts of sodium iodide and tungstate. The conductivity and diffusion of the silver radiotracer Ag/sup 110m/ in solid electrolytes of the alpha-AgI type are measured. The activity distributions in the samples after homogenizing and the temperature dependence of the diffusion coefficients are shown.
