Nucleation and Growth of Lanthanum Tartrate Crystals in Silica Gel 

By H. M. Patil, D.K. Sawant, D.S. Bhavsar, J.H. Patil, K.D. Girase 


Lanthanum tartrate crystals were grown by single diffusion gel growth 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 ageing on the growth of these crystals was studied. The optimum conditions required for the growth of these crystals are worked out. Semitransparent spiky spherulites and dendrite crystals were obtained. An attempt has been made to explain growth mechanism.
