Liquid Lithium Silicate for Concrete Hardener and Dustproof Sealer

Overview of Liquid lithium silicate

Liquid lithium silicate is a type of alkali silicate solution where lithium oxide (Li₂O) is combined with silicon dioxide (SiO₂) in an aqueous medium. It is part of a broader class of alkali silicates, which also includes sodium and potassium silicates. Lithium silicate solutions are known for their unique properties, making them useful in various industrial applications.

Features of Liquid lithium silicate

1. Chemical Composition:
   • Typically expressed as a ratio of Li₂O:SiO₂ (e.g., 1:2 to 1:5).
   • Higher SiO₂ content increases viscosity and film-forming ability.
   • Lower ratios (more Li₂O) enhance solubility and reactivity.
2. Alkaline Nature:
   • pH is highly alkaline (typically 11–13), similar to other alkali silicates.
   • Provides corrosion resistance when used in coatings.
3. Film Formation & Binding Properties:
   • Forms a hard, glass-like silicate matrix upon drying.
   • Used as a binder in refractory materials, paints, and coatings.
4. Thermal & Chemical Stability:
   • Resistant to high temperatures, making it useful in fireproofing applications.
   • Chemically inert to many solvents and acids once cured.
5. Low Viscosity (Compared to Sodium/Potassium Silicates):
   • Lithium silicates generally have lower viscosity at similar concentrations, allowing for better penetration in applications like concrete treatment.

FAQs of Liquid Lithium Silicate

1. What is liquid lithium silicate used for?

Liquid lithium silicate is primarily used for:

• Concrete hardening & dustproofing (reacts with free lime to form a durable surface).
• High-temperature coatings (refractory binders, fireproofing).
• Anti-corrosive zinc-rich paints (binder in primers for steel protection).
• Adhesives & sealants (especially where heat resistance is needed).
• Battery research (as a potential electrolyte component).

2. How does lithium silicate compare to sodium or potassium silicate?

• Lower viscosity → Better penetration into porous materials like concrete.
• Forms harder films → More abrasion-resistant coatings.
• Higher thermal stability → Better for refractory applications.
• More expensive → Used where performance justifies cost.

3. Is lithium silicate corrosive?

• Yes, in liquid form (pH ~11–13), it is alkaline and can irritate skin/eyes.
• Once cured, it forms an inert, non-corrosive glassy matrix.
• Proper handling (gloves, goggles) is recommended during application.

4. Can lithium silicate be diluted with water?

• Yes, it is water-soluble and can be diluted for specific applications (e.g., concrete treatment).
• Avoid excessive dilution, as it may reduce effectiveness.

5. How long does lithium silicate take to cure?

• Drying time: 1–4 hours (depending on temperature/humidity).
• Full curing: 24–72 hours for complete chemical reaction (e.g., with concrete).
• Faster curing than sodium/potassium silicates in some cases.
