Abstract: An inorganic barium chloride dihydrate, alkanine earth metal halide single crystal, was grown by a slow solvent evaporation technique in solution growth method. Highly transparent crystals were grown with the aid of phosphorous acid, which control the optimum pH of the aqueous solution and optimize the growth faster. The harvested crystals were subjected to characterization for revealing its structural, optical, mechanical and thermal properties. Barium chloride dihydrate crystal was confirmed by single crystal X-ray diffraction analysis and the functional groups present in it were identified using Fourier transform infrared analysis, and reported. The linear optical transmittance in the ultraviolet, visible and infrared radiation of wavelength ranging from 200 to 1100 nm was studied and explained in detail. Dielectric studies were made on the crystalline compound to find dielectric permittivity. In order to find mechanical properties such as surface hardness, yield strength, and other relevant properties, Vicker’s microhardness testing was done on the as grown crystal. The thermal stability of the crystalline material was found out using thermal analysis such as Thermogravimetric and Differential thermal analysis.
