Sodium Metasilicate Granules
Granular sodium metasilicate product information for buyers reviewing particle size, handling, detergent compatibility, packing, documents, and RFQ details.
Updated
Short answer
- Sodium metasilicate granules (Na₂SiO₃, CAS 6834-92-0) are the free-flowing solid grade, supplied in two tiers: Superior at Fe ≤0.010% and water-insoluble ≤0.06%, Standard at Fe ≤0.020% and ≤0.20%, both at SiO₂ ≥45.0% and Na₂O ≥50.0%.
- The chemistry is identical to the anhydrous powder; the granular form is chosen for cleaner handling, controlled dust and predictable dosing on automated blending lines, at 18–60 mesh ≥93.0%.
- Zhongzhi Chemical manufactures and exports it from China in 25 kg PP woven bags with PE liner, 50 kg bags and 1,000 kg FIBCs, with COA, SDS and REACH documentation available for buyer review.

Product Overview
Sodium metasilicate granules are a free-flowing Na₂SiO₃ form used where easier handling, controlled dosing, lower dust, and stable storage are important in industrial formulations.
This form is commonly reviewed by detergent plants, cleaning compound producers, ceramic processors, metal treatment users, and distributors that need clear particle-size and packing confirmation before quotation.
Before ordering granular sodium metasilicate, buyers should confirm target mesh size, Na₂O, SiO₂, Fe, water insoluble matter, appearance, packing method, loading quantity, destination port, and required documents.
