Abstract: The chemical notation of the reaction products in the system NaF—AlF₃—Al₂O₃ was reevaluated and its modifications were suggested. Based on these modifications, the equilibrium constants of selected reactions were calculated. Some of the equilibrium constants differed by one or two orders of magnitude from the values of the corresponding original equilibrium constants.

Keywords: oxofluoroaluminates - cryolite - alumina - equilibrium constant
