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