Abstract
The studies carried out over the last decades show that one of the main causes of failure of electrolyzers is the behavior of sodium in the process of aluminum electrolysis and its introduction into the electrolyzer bed. The paper describes the behavior of sodium in the process of aluminum electrolysis with the use of a number of additives in the electrolyte, which have some influence on the electrolysis process and the state of the electrolysis bath.
