Abstract
In present study, single crystals of calcium tartrate (CaTr) were grown by a simple gel technique, using single diffusion method. The optimum growth conditions were optimized by varying various process parameters such as gel concentration, pH of the gel, gel aging, 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 the gel, it was left for aging. After two or three day’s duration, the supernatant calcium chloride of different molarities was poured over the set gel. After 48 to 60 hours of pouring the supernatant, the small nucleation growth was observed below the interface of gel. In the present work few prismatic, semitransparent crystals, semi transparent and some whitish, crystals of calcium tartrate were grown. These crystals were characterized by using EDAX, SEM and UV spectroscopy.
