FREQUENCY DEPENDENCE OF AC CONDUCTIVITY OF DIVALENT OXALATE CRYSTALOXALATE SINGLE CRYSTALS

Characterization of the grown cadmium oxalate single crystals is an essential requirement to describe, confront and explain their various properties. Cadmium oxalate trihydrate (CdC2O4·3H2O) single crystals suitable for the present investigation were grown using controlled diffusion process in silica gels. The investigation on electrical parameters of cadmium oxalate has been carried out to understand the mechanism of charge transport. The crystal shows a very prominent sharp peak at 385 K. This confirms to the dehydration temperature. The dielectric constant for (001) planes remain almost temperature independent upto 450K. It is difficult to distinguish the variation with frequency. The temperature 450K corresponds to generation of complete dehydrated sample of cadmium oxalate, in confirmation of thermal analysis
