Growth and Study of BaTr single crystals by Gel Technique

Suresh Keda Bachhav, Padmakar Arjun Savale and Suresh Trimbak Pawar

In the present investigation, single crystals of Barium tartrate (BaTr) were grown by a simple gel technique using diffusion method. The optimum growth conditions were optimized by varying various parameters such as pH, concentration of the gel solution, setting time of the gel solution and concentration of the reactance. The test tubes were used as crystallization vessels while silica gel as a growth media. Gel was prepared by mixing the solutions acetic acid (CH3COOH), sodium meta silicate (Na2SiO3),barium chloride (BaCl2) and transferred in glass tube of diameter 2.5cm and 15cm in length. The mouth of tube is covered by cotton plug and kept for the setting. After setting the gel, it was left for aging. After two days the supernatant tartaric acid (C4H6O6) of 1M concentration was poured over the set gel by using pipette and kept undisturbed by covering the cotton plug on the mouth of tubes. After 48 hours of pouring the supernatant, the small nucleation growth was observed at below the interface of gel. Good quality spherulites crystals were grown in 45 days. The grown BaTr crystals were observed in small size. These crystals were characterized by using X-ray diffraction and FTIR analysis.
