The method of trimethylsilylation was used to study anion distributions in sodium silicate
solutions with Na2O: SiO2 ratios of 1: 1 and 1: 3.41 at various concentrations. The …

The distributions of anions in solutions of lithium, sodium, potassium, rubidium, caesium,
and tetramethyl-, tetra-n-propyl-, and tetra-n-butyl-ammonium silicate solutions have been …

Homogeneous trimethylsilylation of silicic acid in nonaqueous media was studied. The
silylation process consisted of three steps: acidification of sodium silicate, solvent extraction …

The effect of the addition of tetramethylammonium ions on the distribution of silicate species
in the methanolic solutions was studied by the trimethylsilylation technique …

In concentrated solutions of sodium silicate with SiO2: Na2O ratios ranging from 2: 1 to 4: 1,
about 75% of the silica is present as extremely small particles which increase from 1 to 2 nm …

Polysilicate equilibria in concentrated sodium silicate solutions have been studied using
potentiometric (glass electrode) and 29Si nmr methods. Experimental data cover the ranges …

The application of the technique of trimethylsilylation to mineral silicates is reviewed.
Information can be obtained on the molecular size distribution of the silicate anions and also …

It is possible to prepare organic derivatives of silicate groups in which each terminal oxygen
is blocked by a trimethylsilyl group. This can provide a route for the preparation of new …

Changes in the pH or concentration of sodium silicate solutions produce changes in the
degree of polymerisation of the silicate species, and these have been followed by the …

The chemical species of silica in NaCl solutions of different concentrations were identified by
FAB-MS (fast atom bombardment mass spectrometry). The basic structures of silica species …
