    • A process is provided for producing aluminum in an electrolytic cell containing aluminum chloride dissolved in a molten solvent of higher decomposition potential. The cell has a terminal anode, a terminal cathode and a bipolar electrode arranged to operate with the anode and the cathode, providing interelectrode spaces therebetween. On electrolyzing the cell chlorine is produced on each anode surface thereof and aluminum on each cathode surface, the aluminum being swept from the cathode surface by bath material. In the process, carbonaceous material is provided for use as the electrode. The direction of grain flow constituting the carbonaceous material is determined and the electrode is arranged in the cell such that the direction of electrolysis current flow through the cell is in a direction substantially perpendicular to the direction of grain flow in the electrode.
    • 提供了在含有溶解在较高分解电位的熔融溶剂中的氯化铝的电解槽中生产铝的方法。 电池具有端子阳极,端子阴极和布置成与阳极和阴极一起操作的双极电极,在它们之间提供电极间空间。 在电解电池时,在其每个阳极表面上产生氯,在每个阴极表面上产生铝,铝通过浴材从阴极表面扫过。 在此过程中,提供碳质材料用作电极。 确定构成碳质材料的晶粒流动的方向,并且将电极设置在电池中,使得电解电流流过电池的方向处于与电极中的颗粒流动方向基本垂直的方向。
