1) What is Sodium Silicate (Na₂SiO₃)?
Sodium Silicate (Na₂SiO₃) is an inorganic compound composed of Na₂O and SiO₂. The commercial form is typically a highly viscous liquid solution, appearing white-opaque or slightly blue due to impurities; sometimes available in powder/solid form.
- Alternative names: Sodium silicate, water glass.
- Common density: 40–50° (liquid solution).
- Key properties: Mildly alkaline, pH stabilizing, excellent binding; decomposes with acids (including CO₂) to form silicic gel ⇒ requires airtight storage.

2) Sodium Silicate Applications
2.1. Water Treatment Applications
Stabilizes pH, forms protective anti-corrosion film in pipelines, and aids coagulation-sedimentation. Suitable for boiler water, cooling water, potable water supply, and pre-filtration treatment.
2.2. Construction Applications (waterproofing, hardening)
Penetrates concrete to reduce capillary action, increase surface hardness, and waterproof roofs/basements. Can be combined with specialized additives per structural requirements.
2.3. Ceramics – Glass, Adhesives & Cleaning Agents
Creates ceramic glazes, enhances mechanical strength/heat resistance; used in paper/wood/brick adhesives; component in detergents/dishwashing liquids for water softening and pH stabilization.
3) Usage Guidelines & Safety Precautions
| Purpose | Standard Usage |
|---|---|
| Water treatment | Dilute 1:5 – 1:10 with water; dose according to system flow rate or technical recommendations |
| Concrete waterproofing | Mix with cement water for brushing/spraying or apply directly to cleaned surfaces; test on small area first. |
| Adhesives – Binding | Use undiluted or adjust viscosity as needed; stir thoroughly, avoid contaminants. |
Safety notes: Wear gloves, goggles, and masks when handling. Avoid direct skin/eye contact; rinse thoroughly with water if exposed, flush eyes continuously if contacted and seek medical help. Store in cool, dry, sealed containers away from direct sunlight and CO₂.
