Abstract

A thermodynamic model is developed to describe silicate behavior in solutions containing high concentrations of both NaOH and NaNO₃. Experimental solubility data in such solutions are also presented. The model itself applies Pitzer's ion-interaction approach and involves several aqueous polymeric species. Model predictions compare well with a variety of experimental data-solubilities, NMR results, and pH measurements.
