The viscosity of the molten eutectic mixture of Li2CO3-Na2CO3-K2CO3(reagent grade) has been measured to 900 °C by means of the oscillating crucible technique used for measurements in the absolute mode. The viscosity can be expressed by η (mPa·s) = 0.1012 exp(33400/RT), where R equals 8.3143 J K-1mol-1, and the accuracy limits are better than ±3%. The present results differ markedly from previously published results, and model calculations show that the differences can be understood, In large part, If the presence of a “voids” effect had escaped detection in the earlier work. Results are also reported for a series of measurements with a commercial grade carbonate eutectic mixture.
