The Structure of Aluminum Chloride-Sodium Chloride Melts

Equilibrium constants were calculated for reactions governing the species present at 175C in molten mixtures of aluminum chloride and sodium chloride. The equilibria postulated pertain to formation of the complex ions AlCl4(-), Al2Cl7(-), and Al3Cl1o(-) from Cl(-), AlCl3, and Al2Cl8. Measurements we...

Description
Summary:Equilibrium constants were calculated for reactions governing the species present at 175C in molten mixtures of aluminum chloride and sodium chloride. The equilibria postulated pertain to formation of the complex ions AlCl4(-), Al2Cl7(-), and Al3Cl1o(-) from Cl(-), AlCl3, and Al2Cl8. Measurements were made throughout the concentration range N = 0.498 to N = 0.71. The possibilities of using these concentration cells as high energy density batteries are considered.
