Abstract

The growth of cobalt tartrate crystals was achieved in silica gel by single diffusion method. The growth conditions were optimized by varying various process parameters such as pH of the gel solution, gel concentration, concentration of reactants etc. The test tubes were used as crystallization vessels, while silica gel as growth medium. Gel was prepared by mixing the solution of tartaric acid and sodium meta silicate. After setting of the gel, it was left for aging. After two or three day's duration, the supernatant zinc chloride of different molarities was poured over the set gel. After 48 to 60 hours of pouring the supernatant, small nucleation growth was observed below the interface of gel. Structural study was carried out by XRD; the thermal behavior of the material was studied using thermogravimetry (TG) and differential thermal analysis (DTA). It is observed that the material is thermally stable up to 300c beyond which it decomposes through many stages till the formation of cobalt oxide at 9950c.
