Sodium metasilicate is the chemical substance with formula Na 2 SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na + and the polymeric metasilicate anions [– SiO 2− 3 –] n.
Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cements , coatings, passive fire protection , textile and lumber processing, manufacture of refractory ...
Calcium ions then react with the soluble sodium silicate gel to convert it into solid calcium silicate hydrates (C-S-H). The C-S-H forms a continuous poorly permeable coating at the external surface of the aggregate. The penetrated alkaline solution (NaOH / KOH) converts the remaining siliceous minerals into bulky soluble alkali silicate gel.
Idealized structure of sodium metasilicate. Metasilicates are silicates containing ions of empirical formula SiO 2− 3. Common stoichiometries include M I 2 SiO 3 and M II SiO 3. Metasilicates can be cyclic, usually the hexamer (SiO 3) 12− 6 or chains (SiO 3)n 2−. [1] Common compounds containing metasilicate anion are: Inosilicates
Alternative depiction of a metasilicate chain emphasizing the Si-O bonds. With two shared oxides bound to each silicon, cyclic or polymeric structures can result. The cyclic metasilicate ring Si 6 O 12− 18 is a hexamer of SiO 3 2-. Polymeric silicate anions of can exist also as long chains.
Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K 2 SiO 3 , samples of which contain varying amounts of water . These are white solids or colorless solutions.
Treatment, including IV fluids, medication, and sometimes surgery, can cost between $500 and $1,500. Wet Tail (Hamsters): A severe intestinal disease caused by stress or bacteria. Immediate vet ...
In situ chemical oxidation (ISCO), a form of advanced oxidation process, is an environmental remediation technique used for soil and/or groundwater remediation to lower the concentrations of targeted environmental contaminants to acceptable levels.
