AbstractThe invention comprises an improved cathode for a chloralkali cell having grains of alpha-iron adherent to the surface of the cathode, and a process for making the cathode which comprises depositing grains of alpha-iron onto the surface of an electrically conductive cathode substrate in an electrical cell. The invention also provides a method for lowering the operating voltage of a chloralkali electrolysis cell which comprises adding iron particles to the cathode compartment of the cell.
