CdI 2 has been purified using the zone‐refining technique by giving 20 passes. Single crystals grown from the starting material showed arcing in the X‐ray oscillation photographs whereas it is absent in the crystals grown from the zone refined material. These crystals are found to be of the 4 H type. DC conductivity studies were made on these crystals at various stages of purification. The surface morphology of these crystals have been studied using an optical microscope.
