Abstract
Solid-liquid equilibria in the quinary system Na+, K+‖Br−, SO4 2−, B4O7 2−−H2O at 298 K were measured by isothermal solution saturation method. The solubilities of salts and the densities of saturated solutions in the system were determined. Using the experimental data, phase diagram, Na+ content diagram, water content diagram and density-composition diagram were constructed, respectively. The double salt Na2SO4 · 3K2SO4 (Gla) was found in the quinary system Na+, K+‖Br−, SO4 2−, B4O7 2−−H2O at 298 K. In the phase diagram, there are eleven univariant curves, five invariant points and seven crystallization regions saturated with Na2B4O7 · 10H2O, where the solids are Na2SO4, K2SO4, Na2SO4 · 3K2SO4 (Gla), Na2SO4 · 10H2O, NaBr · 2H2O, KBr and K2B4O7 · 4H2O. NaBr · 2H2O has the highest concentration and strong salting-out effects on other salts.
