Cathode for magnesium production |
摘要 |
Cathode for use in magnesium production by electrolysis of molten salts. The cathode consists of compact molybdenum, tungsten or alloys of these metals or consists of a substrate coated with molybdenum, tungsten or alloys of these metals. The thickness of the coating is at least 10-20 mu m. The substrate can be iron or carbon. Carbon coated with molybdenum, tungsten or alloys of these metals can be used as the cathodic face of a bipolar electrode. The wetting of the cathode by magnesium is improved and the amount of contaminants in the produced metal is reduced.
