The ionic conductivity of nominally pure and doped polycrystalline SnCl2 has been measured, using an ac technique from 50°C to the melting point. Conductivity of the sample showed an activation energy 0f 1.31 eV for the high-temperature region and 0.41 eV for the low-temperature region. In the latter, the conductivity increased by doping with KCl and decreased by doping with YCl3 but the activation energy did not change appreciably. The value of electronic conductivity was observed to be less than 1% of the total conductivity by a dc polarization method at 200°C. The transference number of Sn2+ ion was found to be negligible from tracer diffusion measurements. Therefore the conductivity of SnCl2 crystals is considered to be due to Cl- ions, probably via a vacancy mechanism analogous to PbCl2 with the same crystal structure.
