Abstract
The article discusses the results of determining the possible phase equilibria in geometric images of a five-component reciprocal water-salt system of sulfates, carbonates, sodium bicarbonates and calcium at 100 ºC with subsequent construction of its phase complex diagram. The laws that determine the structure of the phase complex diagram of this system are needed to be obtained for the production of scientific data used both as a reference material and also to create the optimal conditions for the recycling of liquid waste industrial production of aluminum-containing sulfate carbonate and bicarbonate salts of sodium and calcium. It was established that the system under study at 100ºC is characterized by the presence of 31 divariant double saturation fields, 25 monovariant trisaturation curves and 14 invariant points.
Highlights
The phase diagrams for the complex systems are of scientific interest, and necessary for creating optimal conditions for the galurgic processing of natural mineral raw materials and industrial wastes containing sulfates, carbonates, sodium and calcium bicarbonates [1]
A unification of the salt part of the phase diagram, we obtain a schematic diagram for the phase equilibria in the Na,Ca||SO4, CO3,HCO3‐H2O
The translation method applied for the Na,Ca||SO4,CO3,HCO3‐H2O system at 100 °C while transforming the phase equilibria from the level of four-component (A) to the level of five-component (B)
Summary
The phase diagrams for the complex systems are of scientific interest, and necessary for creating optimal conditions for the galurgic processing of natural mineral raw materials and industrial wastes containing sulfates, carbonates, sodium and calcium bicarbonates [1]. The Na,Ca||SO4,CO3,HCO3‐H2O system has not been studied yet at 100 °C. Earlier we studied phase equilibria in this system by the translation method at temperatures of 0 and 50 °C [2, 3]
