Abstract
The invention relates to an anode of a fusion electrolysis furnace for the production of aluminum, which anode consists of a plurality of individual oxide-ceramic elements of stable dimensions. The individual elements have linear cross-sectional dimensions of 2-12 cm. on the current exit surface. These elements have a length which corresponds to 2-20 times the value of the mean linear cross-sectional dimension, they are arranged approximately parallel with a mean distance between outer surfaces of 1-20 mm. and are held together mechanically stably at the end facing the current entry with an electrically conductive device situated outside the molten electrolyte. The anode in bundle configuration, in comparison with oxide-ceramic anodes of large format, has a lower corrosion erosion, is simpler to produce ceramically and has a greater stability to temperature changes.
