The viscosity of the molten eutectic mixture of Li/sub 2/CO/sub 3/-Na/sub 2/CO/sub 3/-K/sub 2/CO/sub 3/(reagent grade) has been measured to 900/sup 0/C by means of the oscillating crucible technique used for measurements in the absolute mode. The viscosity can be expressed by eta (mPa.s) = 0.1012 exp(33400/RT), where R equals 8.3143 J K/sup -1/ mol/sup -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.
