The purpose of this study was to investigate the effect of trace metal like Zinc on Strontium. Trace elements can affect crystallographic properties.Therefore this study was designed to investigate how trace elements influence on crystals and ultimately its physical properties.The single crystal of the strontium chloride and Zinc acetate (SCZA) was grown by Slow evaporation technique using water as a solvent. Good quality crystals were harvested within 20 days. The grown crystals were characterized by Fourier Transform Infrared Spectroscopy (FTIR) were used to confirm the presence of the functional groups of SCZA. Optical property was established by UV-Visible spectrum and the mechanical strength of the grown crystal was estimated by the Vicker’s microhardness test and itwas increased due to the effect of trace metals.
