Strontium Malonate Crystal Grown by Silica Gel Technique

Abstract

Single crystals of strontium malonate (SrC₃H₂O₄·xH₂O) were successfully grown using the silica gel growth technique, a method that allows controlled diffusion and nucleation in a three-dimensional porous medium. Strontium malonate, an alkaline earth metal organic compound, is of interest due to its potential applications in nonlinear optics, luminescent materials, and ion-exchange processes. The growth process was carried out under controlled pH and gel density conditions to optimize crystal size and morphology. The resulting crystals were characterized visually for size, shape, and transparency. The study demonstrates that the silica gel technique is effective for producing well-faceted strontium malonate crystals and provides insight into the nucleation and growth mechanisms of metal-organic crystals in porous media.
