Direct Current Electrical Conductivity Study of the Thermal Decomposition of Copper (II) Monohydrate and Zinc (II) Oxalate Dihydrate.

The solid state reactions involved in the preparation of copper oxide and zinc oxide from copper(II) and Zinc (II) oxalate of monohydrated and dihydrate respectively have been analyzed using direct current electrical conductivity measurement under the atmospheres of static air, dynamic dry nitrogen and dynamic air .The product at each decomposition stage have been characterized by infrared spectroscopy and X-ray powder diffraction. For Copper (II) oxalate monohydrated the final decomposition product in all three atmospheres was found to be CuO and intermediate step product was Cu2O .The Zinc (II) oxalate dehydrated also shows final product in all three atmospheres was found to be ZnO.The conductivity measurement were supplemented with data obtained by chemical thermal (TGA and DTA ),IR spectroscopy and X-ray powder diffraction analysis .
