Experimental study of the density of aqueous solutions of lithium bromide at temperature of up to 250°C in the range of mass concentrations from 30 to 65 %

Abstract

The density of aqueous solutions of lithium bromide was studied by the monochromatic gamma-ray attenuation method at the saturation line from the liquidus temperature of up to 250 °C for five samples with initial concentration of 30,927, 39.706, 50,936, 59.322, and 65.148 mass % of LiBr. The errors of temperature and density measurements were ±0.02÷0.05 °C and ±0.05%, correspondingly. Approximating equations and tables of reference data were obtained for density dependencies on temperature and concentration. Measurement results were compared with published data.
