Magnesium and zinc diffused growth and characterization of strontium L(+) tartrate pentahydrate crystals

Abstract

Single crystals of intrinsic strontium L(+) tartrate (IST), Mg²⁺ doped strontium L(+) tartrate (MDST) and Zn²⁺ doped strontium L(+) tartrate (ZDST) are grown using gel diffusion reaction method. Optimum condition for crystal growth is established by varying gel density, gel pH, concentration and matrix of supernatant solutions. EDAX analysis is made to measure stoichiometric composition and cationic distribution of the grown crystals. Fourier transform infrared (FTIR) and Laser Raman spectral studies unveil various functional groups in the grown crystals. Thermo gravimetric analysis (TGA) reveal decomposition behavior of the crystals for the temperature range of 30-1000^oC. IST, MDST and ZDST crystals inborn with chemical formulae SrC₄H₄O₆.5H₂O, Sr_0.9987Mg_0.0013C₄H₄O₆.5H₂O and Sr_0.9929Zn_0.0071C₄H₄O₆.5H₂O respectively.
