Phase equilibria in the system Na,K||SO4,CO3,HCO3,F–H2O at 0°C in the arcanite (K2SO4) crystallization region
Abstract
The purpose of the study. Phase equilibria were determined by the translation method on geometric images of the system Na,K||SO4,CO3,HCO3,F–H2O at 0°C in the arcanite ((K2SO4) crystallization region. Arcanite was found to participate in the formation 12 divariant fields, 10 monovarint curves, and 3 invariant points. The closed phase diagram (phase complex) of the studied system at 0°C in the arcanite crystallization region was constructed.
Material and methods of research. Phase equilibria of the Na,K||SO4,CO3,HCO3,F–H2O system and the four- and five-component systems forming this six-component system are the scientific basis for the treatment of liquid waste from industrial aluminum production.
Conclusion: From the analysis of the structure of the fragment of the phase equilibrium diagram of the studied system at a temperature of 0°C, it follows that the area of the crystallization of arcanite is characterized by the presence of such a number of geometric elements at the five-component level and at the six-component level.
