The phase diagram of the system KCl-ZnCl2 has been constructed. Values of specific conductivity and density have been determined at eight temperatures in the range 475-650°C. for a series of compositions covering the concentration range. From these data, equivalent conductivities were calculated. The temperature coefficient of conductivity as expressed by the activation energy of ionic migration was calculated at four temperatures for each mixture.
