The authors studied the Li/sub 4/GeO/sub 4/-Li/sub 2/SeO/sub 4/ system as a continuation of an earlier investigation of solid electrolytes on the basis of lithium orthogermanate. The solid electrolytes were synthesized by sintering samples which had been pressed from a mixture of highly disperse powders of Li/sub 2/SeO/sub 4/ and Li/sub 4/GeO/sub 4/. The x-ray phase analysis was performed with a DRON-2 diffractometer in Cu Kalpha-radiation with a nickel filter. Electric resistance was measured with an R502 ac bridge using silver electrodes that had been applied thermochemically with a paste based on silver carbonate. The lowest values of specific resistance are seen near the lower limit of the single-phase region of P-solid solutions. This is in accord with the decisive influence of the concentration of highly mobile carriers (the interstitial lithium ions) on the transport properties of structures similar to gamma-Li/sub 3/PO/sub 4/. The number of interstitial lithium ions increases with decreasing x, and will be highest at the lower limit of the region of existence of P-solid solutions.
