Abstract
A replaceable cathode unit, suitable as a module for the building up of stable, non-deformable cathode systems in electrolyzers for the production of magnesium by melted salt electrolysis, is the form of a straight, longitudinal main cathode with active cathode side surfaces and two shorter transverse cathodes arranged approximately at right angles in relation to the main cathode. One transverse cathode is at the front end of the main cathode, and the other transverse cathode is at the back end of the main cathode.
