抄録

The magnesium electrolyte such as the MgCl2–LiCl system has been studied for determining the density and electrical conductivity.<BR>The electrical conductivity of the present system is found to be more than 2.5 to 2.7 times greater than that of the Dow and I.G. electrolytes.<BR>It is possible to reduce the electrolysis temperature of the present system in comparison with the Dow and I.G. electrolytes, and the differences in density between liquid magnesium and electrolytes are about 0.03 to 0.05 g/cm3 for 14.3 to 10.5 mol% MgCl2.<BR>It is of particular interest that the magnesium is recovered at the bottom of the electrolysis cell in the case of magnesium electrolysis of the MgCl2–LiCl system.
