Technology of magnesium hexafluorosilicate production
Systematic study of parameters of the techological process for producing crystalline magnesium hexafluorosilicate from hexafluorosilic acid and caustic magnesite: reagents concentrations and ratio, temperature of the synthesis and evaporation, order of po
INTERACTION OF Mg(II) CATION WITH SOLUTIONS OF HEXAFLUOROSILICIC ACID AND HEXAFLUOROSILICATE ANIONS
In the production of wet-process phosphoric acid from magnesium carbonate-containing phosphorites interactions between the magnesium cations and fluorine-containing anions take place in the process pulp.Using model neutralization of solutions of hexafluorosilicic acid of various concentrations with basic magnesium carbonate as an example, it has been demonstrated that the composition of solid-phase products depends upon the acidity of the medium: at pH 0.86 MgSiF6*6H2O is formed, whereas at pH 1.70 magnesium fluoride precipitates.
