Abstract. The single crystals of calcium carbonate (calcite), barium carbonate and strontium carbonate have been grown in sodium meta silicate gel using the single and double diffusion methods at room temperature. The X-ray Laue-technique is used to characterize the gel grown calcium carbonate crystal. It has been observed that the gel medium prevents the turbulence and helps the formation of good crystals. Further, the varying density of gel can control nucleation and the growth at each stage that may be observed in a transparent medium. The general chemical reaction is taken in this case.
