Method for preparing magnesium-lead alloy through electrolysis

The invention belongs to the technical field of alloy materials, and concretely discloses a method for preparing magnesium-lead alloy through electrolysis. The method is characterized in that an electrolysis raw material hydrated magnesium chloride is electrolyzed at 600-850DEG C by adopting an electrolysis tank to generate the magnesium-lead alloy at the bottom of the electrolysis tank; and the electrolyte system of the above electrolysis is magnesium chloride +alkali metal chloride or magnesium chloride + alkali metal chloride +alkaline earth metal chloride, and the content of magnesium chloride in the electrolyte system is 5-30wt%. The electrolysis raw material adopting hydrated magnesium chloride not anhydrous magnesium chloride is electrolyzed to prepare the magnesium-lead alloy, so the preparation cost of the magnesium-lead alloy is substantially reduced. The electrolysis temperature adopted in the invention is low, so the volatilization loss of the raw material is small, and the material consumption is small; and the heat and corrosion resistance requirements of the above electrolysis device are reduced, so the cost of the device is reduced.
