SYNTHESIS, MECHANICAL AND THERMO GRAVIMETRIC SPECTROSCOPY STUDIES OF NSTU SINGLE CRYSTAL

Abstract

In the current research, a green coloured Nickel Sulphate Thiourea Urea (NSTU) crystal with physical morphologic size of approximately 3.4 cm width x 3.7cm height size was obtained by slow evaporation method. At room temperature (30˚C) distilled water was used as solvent for the prepared NSTU crystal. Various characterization studies such as FT-IR,XRD, microhardness, UV-Vis and TG-DTA were carried out for the above mentioned single crystal. From these characterizations studies the functional group, crystal structure pattern, the hardness stability by applied load, absorption of wavelength and thermal stability are determined.
