Abstract
A cell for the electrolysis of magnesium at low temperatures and electrical potential using a composite anode consisting of a mixture of an oxygen containing compound of magnesium and a reducing agent with internal conductors extending through the composite mixture to provide low resistance current paths through the highly resistive mixture to the active anode surface. The mixture may be employed in a self-baking mode or be prebaked. Alternatively, the mixture may be in particulate form contained within a porous membrane. A bipolar arrangement may also be employed.
