“Hydrogel-Based Growth of Cobalt Tartrate Single Crystals and Their Morphological Study”

Abstract

Single crystals of cobalt tartrate (CoC₄H₄O₆·xH₂O) were successfully grown using the hydro-silica gel technique, which allows controlled nucleation and slow diffusion of reactants in a three-dimensional porous medium. Cobalt tartrate is a transition metal-organic complex with potential applications in catalysis, magnetic materials, and electrochemical sensors. The growth process was optimized by adjusting gel concentration, reactant molarity, and pH, resulting in well-faceted, transparent to pale pink crystals. The study demonstrates the effectiveness of the hydro-silica gel method for producing high-quality cobalt tartrate crystals and provides insights into their growth mechanism and morphology control.
