Abstract
Anode butts are recycled and used together with petroleum coke and pitch for the manufacture of anodes. The quality of these butts has a strong influence on the properties of the anodes.
For this reason butts of different origins were examined to ascertain what makes a good butt. It was ascertained that good butts are hard, have low sodium contents, a high ignition temperature in air and low reactivities in CO2 and air. Butts of bad quality are soft and very reactive. The butt quality was defined by measuring the physical properties and the contaminations of the butts.
