In a quasi-binary salt system, with CdCl2 as an additive, the maximum values of electroconductivity, ion transport number and diffusion coefficient were found between 20 and 30mol%CdCl2; indicating a maximum in the ionic disordering. The nature of the ionic disordering was considered, and conduction mainly via Cu(I) ions was proved. The X-ray diffraction data revealed the formation of CuCl-based solid solutions at 20 to 30mol%CdCl2. The current efficiency was close to 100%, and Faraday’s laws were obeyed during the coulometric titration of CuCl–CdCl2. The system also had good ceramic properties.
