99.5% Lithium Silicate Powder CAS 10102-24-6 And 22% Lithium Silicate Liquid Industrial Lithium Metasilicate 12627-14-4

Product Introduction

Lithium silicate powder, chemically known as lithium metasilicate (Li₂SiO₃), CAS 10102-24-6, is a high-purity white inorganic silicate powder. It is commonly used as a raw material for lithium silicate solutions, ceramic glazes, welding fluxes, specialty glass and surface treatment products.

The 22% lithium silicate liquid, CAS 12627-14-4, is a stable, alkaline, water-soluble lithium silicate solution. It typically contains approximately 22% total solids and has a higher SiO₂/Li₂O molar ratio, usually in the range of 4.5–5.0. This product is widely promoted as a concrete densifier, surface hardener, dustproofer, and anti-corrosion coating binder.

Both grades are produced under strict quality control and are suitable for domestic and international markets. Custom molar ratios, solids content, pH, and packaging are available upon request.

22% Lithium Silicate Liquid / Lithium Metasilicate Solution — CAS 12627-14-4

Product Functions

• Concrete surface densification and hardening
  Lithium silicate reacts with free calcium hydroxide in concrete to form calcium silicate hydrate, improving surface hardness and abrasion resistance.

• Dustproofing and sealing
  Reduces surface porosity, dusting, and permeability of concrete floors, warehouses, and industrial facilities.

• Improved water and chemical resistance
  Forms a silica-rich layer that reduces water absorption and improves resistance to mild chemicals and staining.

• Alkali-silica reaction mitigation
  Lithium ions help reduce expansion caused by alkali-silica reaction in concrete.

• Anti-corrosion binder
  Used in inorganic zinc-rich coatings and anti-corrosion primers to improve adhesion and film hardness.

• High-temperature and ceramic additive
  Provides lithium and silica components for glazes, refractories, welding fluxes, and specialty glass.

• Regulatable reactivity
  Different molar ratios allow control of reactivity, penetration depth, and film-forming performance.

Application Areas

• Polished concrete and industrial flooring
• Warehouse and logistics center floors
• Parking decks, garages, and commercial flooring
• Cementitious grouts, repair mortars, and self-leveling compounds
• Anti-corrosion coatings and marine coatings
• Inorganic zinc silicate shop primers
• Welding fluxes and electrodes
• Ceramic glazes, porcelain enamels, and refractories
• Specialty glass and glass-ceramic materials
• Catalysts and high-performance inorganic binders

Manufacturing Process

Lithium Silicate Powder / Lithium Metasilicate

1. Raw material preparation
   High-purity lithium hydroxide or lithium carbonate and refined silica are weighed according to the target molar ratio.

2. Mixing and blending
   Raw materials are mixed uniformly in a controlled batch system.

3. High-temperature reaction / sintering
   The mixture is heated at controlled temperature, typically above 1000 °C, to form lithium metasilicate.

4. Cooling and milling
   The reacted mass is cooled, crushed, and milled to the required particle size.

5. Classification and sieving
   The powder is classified to ensure consistent particle size distribution.

6. Quality inspection and packaging
   Finished powder is tested and packed in moisture-proof bags or drums.

22% Lithium Silicate Liquid

1. Reaction
   Lithium hydroxide and silica are reacted in deionized water under controlled temperature and pressure.

2. Filtration and purification
   The solution is filtered to remove insoluble matter and achieve high clarity.

3. Concentration adjustment
   The solution is adjusted to approximately 22% total solids.

4. Molar ratio adjustment
   SiO₂/Li₂O ratio is adjusted to the required range, usually 4.5–5.0.

5. Final inspection and packaging
   The product is tested for pH, density, solids, and viscosity, then packed in drums or IBC tanks.

FAQ

1. What is the difference between lithium silicate powder and 22% lithium silicate liquid?

Lithium silicate powder is typically lithium metasilicate Li₂SiO₃, CAS 10102-24-6, with a molar ratio close to 1.0. The 22% liquid is an aqueous lithium silicate solution, CAS 12627-14-4, with a higher SiO₂/Li₂O molar ratio, usually 4.5–5.0, and about 22% total solids.

2. How is 22% lithium silicate liquid used as a concrete densifier?

It is usually applied by low-pressure spray or roller on clean, cured concrete. The surface is kept wet for 20–30 minutes, excess material is removed, and the floor is polished after drying. Always follow the recommended application rate and trial first.

3. What are the CAS numbers of your products?

• Powder lithium metasilicate: CAS 10102-24-6
• 22% lithium silicate liquid: CAS 12627-14-4

4. Can you provide samples and documents?

Yes. Free samples, Certificate of Analysis, Material Safety Data Sheet, and Technical Data Sheet are available upon request.

5. What packaging options do you offer?

Powder: 25 kg paper/plastic bags, 500 kg bulk bags, or drums.
Liquid: 25 L plastic drums, 200 L HDPE drums, 1000 L IBC tanks.

6. How should lithium silicate products be stored?

Store in tightly sealed containers in a cool, dry, well-ventilated place. Keep away from strong acids. Liquid shelf life is typically 12 months; powder can be stored for 24 months when kept dry.

7. Is lithium silicate hazardous?

Lithium silicate liquid is alkaline. Avoid contact with eyes and skin, use chemical-resistant gloves and safety goggles, and follow the MSDS. It is non-flammable and non-explosive under normal conditions.
