Introduction to Sodium Metasilicate Anhydrous
Sodium Metasilicate Anhydrous, often referred to as “water glass,” is a white, crystalline solid widely used across industries for its strong alkaline nature, cleaning efficiency, and buffering properties. This compound, chemically represented as NazSiO3,plays a pivotal role in detergents, ceramics, paper production, and metal surface treatment.
Key Applications of Sodium Metasilicate Anhydrous
As a binder or adhesive in industrial applications.
In metal treatment and surface cleaning (rust inhibition,degreasing).
In detergents and cleaning products as an alkaline builder and deflocculant.
In water treatment, concrete densifying and soil stabilisation due to its silicate properties.

Frequently Asked Questions( FAQs)
What is the primary use of Sodium Metasilicate Anhydrous?
It is widely used as a cleaning and buffering agent in detergents, ceramics, water treatment, and metal surface processing.
What purity level is ideal for industrial applications?
For most industries, a purity level of ≥99% ensures optimal performance and stability.
What is the difference between sodium metasilicate anhydrous and hydrated forms?
The anhydrous form(CAS 6834-92-0) has no water of crystallization. The hydrated forms (such as pentahydrate or nonahydrate) contain water molecules in their crystal structure,affecting bulk weight, reactivity, and application performance.
Is it safe to ship sodium metasilicate anhydrous internationally?
Yes, but you must follow proper packaging (often UN packing group III for corrosive solids), proper labeling (hazard class 8 for corrosives), and export/import regulatory compliance. Suppliers with experience in international shipments reduce risk.
How can I ensure long-term supply stability for Sodium Metasilicate Anhydrous?
Build a relationship with a reliable supplier, secure supply contracts or agreements.
