The present reseach is carried out to produce magnesium, containing some per cent of manganese, directly from the fused electrolyte consisting of MgCl_2 and MnCl_2,or of MgCl_2 and MnF_2. The solubility of manganese in liquid magnesium is firstly determined; the decomposition voltage of MnCl_2 is found to be derived from the equation E(v)=1.98-4×(10)^<-4> (t-650°); the equilibrium constant K_<Mn> of the reaction Mg+MnCl_2⇄MgCl_2+Mn is calculated to be 2.09×(10)^5 at 750℃, utilising the above decomposition voltage; the highest manganese content of magnesium is obtained at the mol fraction of MnCl_2 : MgCl_2=0.013 and also at the mol fraction of MgCl_2 : MnF_2=0.013,and the best result is gained at a current density of 0.7 amp/(cm)^2; in either case the manganese content of the metal can not be reached to the saturation value of it at that temperature.
