1) What is Sodium Silicate (Na₂SiO₃)?
Sodium Silicate (Na₂SiO₃) is an inorganic compound composed of Na₂O and SiO₂. The common commercial form is a highly viscous liquid solution, milky white or slightly green due to impurities; sometimes it is a solid powder/block.
- Other name: Sodium silicate, liquid glass.
- Common density: 40–50° (liquid solution).
- Outstanding features: Mild alkaline, stable pH, good adhesion; easily decomposed by acids (including CO₂) to form silicic gel ⇒ need to be kept sealed.

2) Sodium Silicate Applications
2.1. Application in water treatment
Stabilizes pH, creates a protective film against pipeline corrosion and supports coagulation and sedimentation. Suitable for boiler water, cooling water, domestic water supply and pre-treatment before filtration.
2.2. Applications in construction (waterproofing, reinforcement)
Penetrates into concrete to reduce capillaries, increase surface hardness, support waterproofing of roofs and basements. Specialized additives can be combined according to structural requirements.
2.3. Ceramics – glass, adhesives & detergents
Creates enamel, increases mechanical strength/heat resistance; glues for paper, wood, unburnt bricks; ingredients in laundry detergent/dishwashing liquid thanks to its ability to soften water and stabilize pH.
3) How to use & safety notes
| Purpose | Common uses |
|---|---|
| Water treatment | Mix 1:5 – 1:10 with water; add according to system flow or technical recommendations |
| Concrete waterproofing | Mix with cement water to brush/spray or spray directly onto a clean surface; test on a small area first. |
| Glue – adhesive | Use pure or dilute to required viscosity; stir well to avoid impurities. |
Safety Note: Wear gloves, glasses, and mask when handling. Avoid direct contact with skin/eyes; if splashed, rinse with plenty of clean water. If in eyes, rinse with water continuously and seek medical attention. Store in a cool, dry place, tightly closed, away from direct sunlight and CO₂.
