Abstract

The ultimate life of an aluminum reduction cell cathode is dependent on the thickness of the carbon above the collector bars and the erosion rate of the carbon. By measuring the erosion rate and knowing the thickness of the carbon above the collector bars, plants can determine their ultimate potlife. However, few cathodes fail due to erosion on a regular basis; other determinants affect potlife. Cathode design and the cell operation are both equally important in determining cathode life.
