Abstract: | Ionic conductivity of KBrxI1?x(0?x?1) mixed crystals, σx, has been measured as a function of temperature in the range of 370°C to close to their melting points. The variation in conductivity, σx, with composition in the intrinsic region was found to be non-linear, having a maximum value at x=0.3. The maximum conductivity of KBrxI1?x mixed crystals was never far outside the range of conductivity of the component crystals. Several expressions of the relative conductivity, σx/σ1 (σ1 refers to KBr) have been suggested. |
