Sodium Silicate Hydrate Powder (Meta) Extrapure 500 gr

SKU : O-5298.0500
CAS : 13517-24-3
Formula : Na2O3Si.9H2O
Grade : Extrapure

Primary Applications :

  • Synthesis of Zeolites and Silica Gels: In material science, this highly pure compound is a prime precursor for synthesizing synthetic zeolites (porous aluminosilicate minerals used as molecular sieves), specialized catalysts, and high-purity silica gels.

  • Geopolymer and Advanced Cement Research: Civil engineers and chemists use ultrapure sodium metasilicate as an alkaline activator to study geopolymers and eco-friendly alternatives to traditional Portland cement.

  • Buffer and Cleaning Formulation Standards: Because its aqueous solution is strongly alkaline but possesses excellent buffering capacity, it is used to calibrate automated industrial cleaning systems or prepare standardized alkaline washing solutions in chemical testing.

  • Fixative in Histology: In niche biological staining and preservation techniques, it sometimes acts as a stabilizing mordant or fixative agent.

Sodium Silicate Hydrate Powder (Meta) Extrapure is a high-purity, laboratory-grade crystalline form of sodium metasilicate. While liquid sodium silicates are often referred to colloquially as “water glass,” this specific solid metasilicate is a well-defined chemical compound utilized in analytical chemistry, material science, and specialized synthesis.he “(Meta)” Designation: Silicates can form various structural configurations depending on the ratio of silicon to oxygen. A metasilicate features a strict 1:3 ratio of silicon to oxygen (SiO32-). Structurally, it is made up of polymeric chains of corner-sharing silica tetrahedra.

The “Hydrate Powder” Advantage: Liquid sodium silicates are often complex, non-stoichiometric mixtures of variable compositions. By producing it as a crystalline hydrate powder, manufacturers provide a stable, precisely weighable solid with a predictable chemical behavior and molecular weight.

“Extrapure” Grade: This tier mandates a high purity profile (typically ≥ 98%-99% pure substance). Strict limits are placed on disruptive contaminants like heavy metals, iron, chlorides, and sulfates, making it suitable for rigorous laboratory protocols rather than rough industrial tasks.
