Abstract
The features of the structure formation processes of potassium sulfate and chloride dispersions in the presence of various binding additives have been studied. It has been shown that the process of structure formation proceeds most effectively in the presence of a complex additive containing a finely dispersed clay component and a high molecular weight polymer. Mechanism of structure formation and the optimized process of additive introduction into the dispersed system is discussed.
