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 ≥ $\ge 98\%-99\%$ 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.
