Ionic Conductivity of Cuprous Chloride Containing Cuprous Sulfide

The electrical conductivity of undoped cuprous chloride and cuprous chlo-ride containing cuprous sulfide as an impurity in concentrations between 0.20 and 1.0 mole percent (m/o) has been measured as a function of temperature between 60 ~ and 370 ~ using the a-c method. The results have been analyzed to obtain the values of the energies of formation and migration, mobility of copper interstitial ions, and concentrations of FrenkeI defects. The solu-bil ity l imit of cuprous sulfide in cuprous chloride has also been determined by using electrical conductivity measurements and x-ray diffraction. Electrical conductivity measurements of cuprous chloride have been measured (1, 2). However, infor-mation on the concentration and mobility of ionic de-fects in cuprous chloride has not yet been reported. The predominant lattice defects in ionic crystals have been conveniently investigated by measuring the ioni
