Abstract
An experimental study on phase equilibria at 288 K in the quinary system Li + + Na + + K + + CO 3 2- + B 4 O 7 2- + H 2 O was done by the isothermal solution saturation method. Equilibrium solubilities and properties such as the density, electrical conductivity, and pH of the equilibrium solution were determined experimentally. According to the experimental data, the equilibrium phase diagram saturated with Li 2 CO 3 was constructed. The phase diagram of the quinary system has four invariant points, nine univariant curves, and six crystallization fields (K 2 CO 3 .3/2H 2 O, K 2 B 4 O 7 .4H 2 O, Na 2 B 4 O 7 .10H 2 O, Na 2 CO 3 . 10H 2 O, NaKCO 3 .6H 2 O, and Li 2 B 4 O 7 .3H 2 O). Potassium carbonate (K 2 CO 3 .3/2H 2 O) has the smallest crystallization field. The borates (K 2 B 4 O 7 .4H 2 O, Li 2 B 4 O 7 .3H 2 O, and Na 2 B 4 O 7 .10H 2 O) have larger crystallization fields than the others. The double salt NaKCO 3 .6H 2 O was found in the quinary system.
