Abstract

Surface tension and viscosity of the system (LiF–NaF–KF)eut–K2ZrF6 were measured in its entire concentration range. Surface tension was measured by the maximal bubble pressure method, and viscosity was measured using the computerized torsion pendulum method. Concentration dependencies of both quantities were calculated for three selected temperatures T = 1,123, 1,173, and 1,223 K on the basis of the experimental data. The values of the surface tension lie in the region 96–160 mN m−1 and the values of the viscosity are in the region 0.86–3.06 mPa s.
