Abstract

Quantitative ²⁹Si FT n.m.r. spectra of sodium silicate solutions are used to characterize the distribution of soluble silicate species as the solution composition is changed. The silicate ratios and concentrations used are those of interest in the study of compositional influence on zeolite synthesis [1-3 mol% SiO₂; SiO₂ Na₂O = 1-3]. The concentration of each species depends strongly on the silicate ratio and can be maximized by selection of that ratio. Over the range studied, dependence of the species distribution on silicate concentration is considerably less dramatic. Comparisons are made with the limited previous data.
