Summary
New experimental data for the viscosity of molten lithium nitrate from its melting point up to about 700 K are reported. The measurements were taken, for the first time, with an oscillating-cup viscometer with an estimated uncertainty of 3 %. The obtained data were compared with previous works. It was concluded that there are still large discrepancies between different sets of data. Our data follow the Arrhenius behavior with an activation energy for viscous flow of Eη= 19.3 kJ·mol−1, slightly higher than previous recommendations.
