摘要：

Phase diagram and ionic conductivity of KBr-NaBr mixed crystals system have been studied over the entire composition and stable temperature range. A maximum conductivity enhancement by a factor of 25 with respect to pure KBr, and 8 with respect to pure NaBr, is obtained for the K0.5Na0.5Br solid solution at 500-degrees-C. The conductivity values are found to follow the melting (solidus) temperature in a correlated manner. The minimum in the solidus curve of the phase diagram is observed between 43 and 72 mole% NaBr at 615-degrees-C.
