CAS 1343-98-2: Silicic acid

Silicic acid hydrate is used for studying neurodegenerative diseases due to its ability to inhibit aluminum uptake. It is utilized for the manufacture catalyst and catalyst carrier. It is involved in tungsten filament production as chemical reagent and flux. Further, it is used for oil and wax decoloring. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Silicic acid is a mineral that occurs naturally in the earth's crust. It is used for the treatment of wastewater and industrial effluents due to its high adsorption capacity and chemical stability. Silicic acid is an ionized, acidic compound with a redox potential of -1.8 V, which can be used as an alternative to hydrochloric acid in biological treatment systems. The uptake mechanism of silicic acid is not well understood, but it has been observed to occur via membrane channels and electrostatic interactions with negatively charged particles. The uptake rate of silicic acid depends on particle size and concentration, with higher concentrations leading to greater uptake rates. Silica is also used in the production of many products such as glass, ceramics, and silicon chips.
