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.
Separation of live and dead fine roots is a critical process in studies of fine root dynamics, but many studies use subjective visual cues during time-consuming hand sorting of root samples, or do not attempt separation at all. Here we describe a method for separating fine roots from mangrove forests using solutions of colloidal silica. The method removed …

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.
Weston, MI – Evonik is building a new plant to produce ultra-high purity colloidal silica at its site in Weston, Michigan, USA which is expected to generate a total capital spending of $7.9 million in 2023 and 2024. The plant, which is expected to come onstream in 2024, will be the first of its kind in North America.
Evonik has revealed that it is building a $7.9 million plant to produce ultra-high purity colloidal silica at its site in Weston, Michigan. Due onstream in 2024, this will be the first of its kind in North America. The investment was supported by a $900,000 performance-based grant under the Michigan Business Development Programme.
OCCURRENCE AND FORM. The occurrence of Si within the plant is a result of its uptake, in the form of soluble Si(OH) 4 or Si(OH) 3 O −, from the soil and its controlled polymerization at a final location.However, the ability of a plant to accumulate Si varies greatly between species (0·1–10 % of shoot dry weight) and extensive analysis of Si …
Continuous monitoring of ultra-low levels of silica in locations throughout the plant helps to manage power plant efficiency and reduce downtime by avoiding costly plant shutdowns and repairs. Continuous on-line silica analyzers provide dependable monitoring and protect against the introduction of harmful levels of silica into the steam cycle.

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.

Silica gel is a rigid three-dimensional network of colloidal silica and is classified as aquagel (pores are filled with water), xerogel (aqueous phase in the pores is removed by evaporation), or aerogel (solvent is removed by supercritical extraction), depending on how they are made (Kalapathy et al., 2000).
