Anodes with the electrolysis cell are created of carbon—essentially the most resistant material towards fluoride corrosion—and possibly bake at the process or are prebaked. The previous, also called Söderberg anodes, are much less electricity-productive and fumes introduced in the course of baking are high-priced to collect, And that's why they are being replaced by prebaked anodes Despite the fact that they conserve the facility, Strength, and labor to prebake the cathodes. Carbon for anodes need to be preferably pure in order that neither aluminium nor the electrolyte is contaminated with ash.
