Abstract: The nickel sulphate doped mixed sodium chlorate and sodium bromate mixed crystal is grown by slow evaporation solution growth technique at room temperature. The grown crystal was subjected to XRD, UV, FTIR, SEM, TG/DTA, Microhardness and SHG analysis. Characterization studies reveal that the grown crystal forms cubic system with space group P213. The crystal possesses less absorption in the UV-Visible region. The presence of various functional groups has been identified from FTIR studies with their vibrating frequencies. The second harmonic generation efficiency was also determined. The mechanical property was studied by microhardness.

Keywords: XRD, UV, FTIR, SEM, TG/DTA, Microhardness and SHG.
