Enhancement Mechanical Properties of Barium Chloride by Adding Copper Chloride using Ultrasonic Technique

Abstract

Some of physical properties of BaCl2 dissolves in distilled water had been studied at different concentrations (0.05%, 0.1%, 0.15%, 0.2%, 0.25% and 0.3%) (gm./ml) before and after adding (0.3)gm of CuCl2 for all concentrations , the mechanical properties such as ultrasonic velocity had been measured by ultrasonic waves system at frequency 25 KHz, other mechanical properties had been calculated such as absorption coefficient of ultrasonic waves, relaxation time, relaxation amplitude, specific acoustic impedance, compressibility and bulk modules. The results show that all these properties are increasing with the increase of the polymer concentration except compressibility is decreasing with the increase of the concentration; results show that when adding CuCl2  these properties are increasing except compressibility is decreasing. Results also shows that adding CuCl2 to BaCl2 enhances the ultrasonic absorption coefficient as a result of high values after addition.
