Nucleation and growth of barium tartrate crystals in silica gel

摘要

Barium tartrate crystals were grown by single diffusion gel technique in a sodium metasilicate gel media at ambient temperature. The effect of various parameters like pH of the gel, gel density, Concentration of reactants, gel aging on the growth of these crystals was studied. The optimum conditions required for the growth of these crystals are worked out. Opaque, whitish, star shaped crystals were obtained. An attempt has been made to explain growth mechanism.
