Synthesis, Structural, Optical, Thermal and Electrical Properties of Urea Sulphamic Acid (USA) Single Crystal

Abstract

Single crystals of Urea Sulphamic acid (USA) have been grown by the slow evaporation technique at room temperature using aqueous solution. The single crystal PXRD study confirms orthorhombic p system for the grown crystal. The functional groups present in the grown crystal have been identified by FTIR and FT-Raman analyses. The optical properties of the USA crystal were determined using UV-Visible spectroscopy. Optical constants such as the reflectance, the refractive index, the extinction coefficient, electric susceptibility were determined from UV-Visible spectroscopy. The thermal stability of the crystal was determined from thermo gravimetric and differential thermal analysis curve. The dielectric constant and the dielectric loss were measured as a function of different frequencies and temperatures. The AC electrical conductivity study revealed that the conduction depended both on the frequency and the temperature.
