Abstract

In 1988, reference correlations for the viscosity of a selection of molten inorganic salts were proposed by Janz and have been used extensively. During the last 31 years, many additional measurements have been published. In a very recent paper, new reference correlations for the thermal conductivity of 13 inorganic molten salts were proposed. In this paper, reference correlations for the viscosity of those same salts are examined. All available experimental data for the viscosity of 13 inorganic molten salts have been critically examined with the intention of establishing improved or new reference viscosity correlations. All experimental data have been categorized into primary and secondary data according to the quality of measurement specified by a series of criteria. Standard reference correlations are proposed for the following molten salts (with estimated uncertainties at the 95 % confidence level given in parentheses): LiNO3 (6.7 %), NaNO3 (3.0 %), KNO3 (3.0 %), NaBr (1.6 %), KBr (2.0 %), RbBr (2.2 %), LiCl (3.7 %), NaCl (2.4 %), KCl (1.6 %), RbCl (3.6 %), CsCl (1.1 %), NaI (1.5 %), and RbI (1.5 %).
