Abstract. Strontium tartrate (SrC₄H₄O₆) single crystals were grown by gel growth technique using sodium meta silicate gel. The grown single crystals were transparent having dimension of 2×2×1 mm³. The powder X-ray diffraction (XRD) of the as-grown single crystals showed them to possess monoclinic crystal structure. The lattice parameters were in good agreement with the reported data. The Fourier transform infrared spectroscopy (FTIR) analysis exhibited presence of varied bonds related to molecular structure of strontium tartrate. The surface microstructure study substantiated layer growth mechanism to be prevalent in the present gel grown single crystals. The thermogravimetric (TG), differential thermogravimetric (DTA) and differential thermal (DTA) analysis of the as-grown strontium tartrate single crystals shows that the crystals are thermally stable in the temperature range from room temperature to 390 K. Above 390 K the as-grown crystals decomposes by three steps weight loss. The thermodynamic parameters like activation energy, activation enthalpy, activation entropy and Gibbs free energy were evaluated using the thermographs employing Broido and Coats-Redfern relations. The obtained results are deliberated in details.
