The fast development in the field of optoelectronics necessitates the search for new and efficient NLO crystal materials, which can be used for optoelectronics applications, such as optical computing, optical data storage, optical communication and electro optic shutters. For the fulfilment of these applications, crystals of calcium tartrate were grown by a simple gel technique using single diffusion method. The optimum growth conditions were established by various parameters such as pH of gel solution, gel concentration, gel setting time, concentration of reactants etc. Crystals having different morphologies and habits were obtained. The crystal size is about 5 x 4 x 3 mm. Calcium tartrate crystals are found to be orthorhombic with lattice parameters: a = 9.45900 Å, b = 6.46400Å, c = 5.39600Å. The crystals were characterized by using XRD, TGA and DTA techniques.
