Thermal and electrical properties of manganese (II) oxalate dihydrate and cadmium (II) oxalate monohydrate

The thermal decomposition of MnC 2O 4·2H 2O and CdC 2O 4·H 2O have been studied by two probe direct current electrical conductivity measurements under the atmospheres of static air, dynamic dry nitrogen and dynamic air. The products at each decomposition stage have been characterized by infrared spe...

Description
Summary:The thermal decomposition of MnC 2O 4·2H 2O and CdC 2O 4·H 2O have been studied by two probe direct current electrical conductivity measurements under the atmospheres of static air, dynamic dry nitrogen and dynamic air. The products at each decomposition stage have been characterized by infrared spectroscopy and X-ray powder diffraction. The electrical conductivity measurements were found to give additional information on the solid-state reaction as compared to that obtained from conventional thermal analytical techniques (such as TG and DTA).
