Undoped and Zr-doped PbI single crystals were obtained by modified Bridgman- Stockbarger technique. The limit of Zr solubility in PbI2 was estimated The dc conductivity of the grown single crystals as well as the influence of type and material of electric contacts on the PbI2 conductivity were studied, surface and bulk electrical conductivity contributions were separated. The conductivity was shown to increase with a very small activation energy with heating at Т373 K or to be practically independent of temperature. Above 443-483 K conductivity varies with temperature with Еа0.93 – 1.0 eV.
