Three physicochemical properties have been investigated for LiCl-NaCl-ZnCl2 molten system in restricted concentration range up to xZnCl2=0.20. Surface tension, electrical conductivity and viscosity have been determined using maximum bubble pressure method, method based on the principle of phase shift measurement and torsion pendulum method. Concentration dependencies of these properties have been calculated for 923, 973 a 1023K and plotted for 973K. Results have shown that the presence of zinc chloride does not significantly influence determined physico-chemical properties and their change is gradual.
