FORMATION OF COBALTITE BY THERMAL DECOMPOSITION OF NICKEL–COBALT TARTARATE

Dr. P. S. Shah, Dr. F. V. Dandawate

Abstract :

 The solutions of nickel sulphate hexahydrate and cobalt sulphate heptahydrate were well stirred.  Then 10% sodium tartarate was added at appropriate pH to get nickel–cobalt tartarate monohydrate.  The metal analysis of this tartarate compound was carried out by atomic absorption spectroscopy (AAS).  The elemental analysis of carbon and hydrogen was done by the microanalytical technique.  The thermo gravimetric analysis (TGA), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) of tartarate compound were done under a static air atmosphere. The intermediate compounds were analyzed.  The TGA, DTG and DTA measurements of nickel–cobalt tartarate monohydrate show first the dehydration and then decomposition of carbonate yields nickel cobaltite.
