Epsomite (MgSO 4 .7H 2 O) is a hydrogen bonded crystal having a wide range of applications in various fields. Pure and glycine added Epsomite (a total of six) single crystals have been grown and characterized in order to investigate the effect of glycine as an impurity on the properties of Epsomite crystals.The densities and lattice parameters observed indicate that the impurity molecules have entered into the crystal matrix. The grown crystals exhibit good optical transparency in the wavelength range 210-1100 nm. Second harmonic generation measurements indicate that they are nonlinear optically active. Results obtained through microhardness measurements follow the normal indentation size effect. Electrical (AC and DC) measurements indicate that all the six crystals grown in the present study exhibit a normal dielectric behavior and the electrical conduction is understood to be due to the protonic movement. Moreover, glycine addition is found to reduce ε r value significantly indicating the possibility of Epsomite crystal becoming a low-ε r value dielectric material.

Single crystals of pure and doped (Cd 2+ , Hg 2+ and histidine) magnesium sulphate heptahydrate (MgSO 4 .7H 2 O) crystals were grown by slow evaporation method. The entry of the dopants into the crystal lattice was confirmed by energy dispersive x-ray (EDX) analysis. The infrared spectra recorded for histidine doped magnesium sulphate crystals showed the presence of amino group in the grown crystal. The powder x-ray data was indexed and there was no significant lattice distortion was observed due to the addition of dopants. The thermograms recorded for the grown crystals showed that these crystals were thermally unstable and decompose through many stages. UV-Vis spectral studies showed that the crystals were transparent in the visible region.

Growth kinetics of zinc (tris) thiourea sulphate (ZTS) crystals investigated as a function of supersaturation is reported in this communication. Crystal growth rates were investigated normal to the (100), (010) and (001) faces under growth conditions employed for bulk crystal growth. The growth rates normal to (010) and (100) were found to follow the continuous growth model (R G = Cσ) with respect to the supersaturation whereas the growth rates normal to (001) was found to satisfy birth and spread (B+S) model (R G = Aσ 5/6 exp(-B/σ)). The growth rates observed normal to the studied face are in agreement with the growth mechanism predicted from the estimated α (Jackson) factor.
