Electrical conductivities of MgCl2-ACl (A = Li, Na, K and Cs) binary melts were measured at temperature from liquidus to 1200K by AC bridge method. Molar conductivities show negative deviations from the additivitity. The deviation increases as the radius of alkali cation in AC1 increases from Li+ to Cs+. The maximum negative deviation is found at the composition of about XAC1 = 2/3. Apparent activation energies for electrical conduction at XAC1 = 2/3 increase with an increase in radius of alkali cation and are closely related to the interaction parameter derived from heat of mixing of MgCl2-ACl binary melts. The electrical conductivity of MgCl2-ACl binary melt is greatly affected by complex formation of MgCl42_, because transport of other ions is prevented by MgCl42- of large size and low mobility.
