Silicic Acid Powder CAS 1343-98-2

Silica is an inorganic substance with the chemical formula of H2SiO3. It is a weak acid, and its salt has hydrolysis in aqueous solution. Free silicic acid, including orthosilicic acid (H4SiO4), metasilicic acid (H2SiO3) and disilicic acid (H2Si2O5), is weak in acidity. Ionization equilibrium constant of metasilicic acid K1=2 × From 10 to 10 (room temperature), orthosilicic acid is stable in the range of pH=2-3. However, if the supersaturated H4SiO4 solution is placed for a long time, there will be amorphous silica precipitation, which is milky white precipitation, and appears as colloidal particles, precipitates or gel. Part of the water in the gel evaporates to obtain a porous dry solid gel, namely the common silica gel. The silicic acid gel has strong adsorption, and can be used as a moisture absorption desiccant, a catalyst, or a carrier of other catalysts.

It is used as a desiccant for various industrial gases and a moisture-proof agent for equipment, instruments, medicines and foods, etc. It is used as an air humidity regulator and environmental relative humidity indicator in laboratories, factory workshops and public places. It is used as an ion exchanger in the water treatment industry; It is used in the petrochemical field for the refining and separation of products and the dehydration and refining of organic products. It is used as a catalyst and carrier in the production of chemical products such as phthalic anhydride, aniline, maleic anhydride, acrylonitrile and butadiene rubber. It is used as a carrier for toxic gases in atmospheric monitoring and as a carrier for chromatography, etc.
