Abstrakt: The disadvantages of the use of aluminum trifluoride as a correcting additive to the commercial electrolytes of aluminum production are discussed. In pot rooms equipped with electrolysis cells having self-calcinating anodes and a dry gas cleaning system, sodium tetrafluoroaluminate can be a challenging alternative for aluminum trifluoride. In the range of acid electrolytes, sodium tetrafluoroaluminate is the dominating component of a melt and gaseous phase. [ABSTRACT FROM AUTHOR]
