DKIC produces colloidal silica with particle size ranging between 7 to 35 nanometers. These stable aqueous dispersions of colloidal silica are available in silica concentrations from 20 to 50 weight%. Colloidal Silica is readily soluble in water in all proportions. It has a low viscosity, which is comparable to that of water.
Standard colloidal silica is stable at a pH from 8 - 10.5 and carries an anionic surface charge that is stabilized with sodium or ammonium. In certain grades, some of the silicon atoms in the silica particle are replaced with aluminate ions to allow for enhanced stability in a wider pH range, usually 3.5 - 10.5.

No tests ever showed *reactive* silica in the demin water, but colloidal silica does not show up on such tests. Colloidal silica is notoriously difficult to detect in low (ppb) concentrations, and only a few labs can provide analyses. Even those lab results have poor resolution. The cutoff for detectability at one lab was 100 ppb colloidal silica.

Colloidal silica (CS) is a kind of nanomaterial used in soil/rock grouting techniques in different branches of civil engineering. Many studies have recently been performed to investigate the potential of CS in improving the mechanical behavior of cohesionless soils and mitigating the risk of seismic liquefaction in urbanized areas. CS grout is chemically …

Nowadays, colloidal silica dispersions are determined/introduced by pH, concentration, particle size, and surface charge [18]. Colloidal silica could be used for a variety of purposes, including drug carriers [19], binders for paints [20], composite materials [21, 22], ceramics [23], and electrical insulators [24].
