Abstract

In order to solve the problems in Mg-Sr alloy prepared by direct reaction method , such as oxidation loss, high energy consumption and low electrolytic current efficiency of only strontium, Mg-Sr alloy was prepared by molten salt electrolysis with MgCl₂-SrCl₂-KCl molten salt. The influences on the electrolytic efficiency and Sr content produced by electrolytic temperature, current intensity and electrolytic time and MgCl₂ concentration were studied. The results show that Mg-Sr alloy was feasible at the temperature of 700 °C with 8A/cm² cathodic current density, 10 % MgCl₂ concentration, 73 % SrCl₂ concentration and Sr content is 35 %. The current efficiency of electrolytic process reached 85 % which was much higher than that of only strontium electrolytic preparation. When the Sr proportion of cathode precipitated Mg-Sr alloy increased gradually to about 45 %, the Mg-Sr alloying ability weakened, the Sr loss ratio became larger and the current efficiency reduced.
