Abstract:  The viscosity of molten binary Na₃AlF₆ —Al₂0₃,  Na₃AlF₆ —LiF, Na₃AlF₆  — Li₃AlFe, Na₃AlFe —MgF₂, Na₃AlF₆  —CaF₂, and Na₃AlFe —NaCl was measured using the torsion pendulum method. With regard to the electrolytic Al production, the above systems were investigated in the range of high concentrations of cryolite. The measurement was carried out in the temperature interval 850 to 1050°C. The experimental results were interpreted with respect to recent ideas on the structure of melts on the cryolite basis.
