Solubility in System Na,Ca∥SO4,CO3–H2O at 50°C

详细

Water solubility at 50°C was studied in the four-component water-salt system comprised of sodium and calcium sulfates and carbonates in order to determine the concentration parameters of solution and crystallization of the constituent salts and to experimentally verify the phase equilibria in the geometric images of the system predicted previously by the translation method. The prediction of possible phase equilibria in geometric images of the system, followed by plotting of its phase diagram, appreciably decreases the time and material costs of experimentation and improves the reliability of results. Our results can serve both as reference information and as a scientific base for optimizing the processing parameters of natural and technical items, in particular, the recycling of salts from liquid waste of aluminum production facilities.
