Instant Sodium Silicate Powder
Instant sodium silicate powder (LGS-20 and LGS-30): modulus, documents and RFQ fields. Sodium metasilicate anhydrous and pentahydrate are quoted on the same form.
Updated
Short answer
- Instant sodium silicate powder (Na₂O·nSiO₂, CAS 1344-09-8) is supplied as LGS-20 (modulus ≈ 1.9–2.1) and LGS-30 (modulus ≈ 2.9–3.1).
- Modulus sets alkalinity and silica behaviour, which is why concrete chemicals, foundry binders, drilling fluids and detergent systems each name a grade rather than a generic silicate.
- Zhongzhi Chemical also supplies sodium metasilicate anhydrous and sodium metasilicate pentahydrate.
- SDS is downloadable.
- No TDS is published for instant powder.
- Packing and quantity are confirmed on the RFQ.

Product Overview
Instant sodium silicate powder is the solid sodium silicate reviewed for industrial formulations, binder systems, construction chemicals, paper production and water treatment.
The purchasing decision is the powder grade — LGS-20 or LGS-30 — followed by appearance, packing, destination and documents.
Sodium metasilicate anhydrous and sodium metasilicate pentahydrate are separate grades. Name the one the formulation uses so the quotation matches the CAS.

Frequently Asked Questions
What is the modulus of instant sodium silicate powder and why does it matter?
Modulus is the molar ratio of SiO₂ to Na₂O. It governs alkalinity and silica behaviour, so the grade — not a generic silicate name — decides fit. LGS-20 is ≈ 1.9–2.1 and LGS-30 is ≈ 2.9–3.1. Name the grade and the application on the RFQ.
Which solid silicates do you supply?
Instant sodium silicate powder (LGS-20 and LGS-30), sodium metasilicate anhydrous, and sodium metasilicate pentahydrate. State the grade on the RFQ so the quotation matches the CAS and the modulus.
What instant powder grades do you offer?
LGS-20 and LGS-30. No TDS is published for either grade. Sodium metasilicate anhydrous and pentahydrate TDS files are on Downloads.
What is instant sodium silicate powder used for?
Buyers review it for detergent and soap manufacturing, concrete and cement additive systems, foundry binders and refractories, paper and pulp processing, and water treatment or soil stabilisation. The grade follows the application.
How is instant sodium silicate powder packed and what is the MOQ?
Packing and minimum order quantity are confirmed on the RFQ against the grade, the application and the destination.
