Alkaline Silica Sol Grade Comparison
Peak-tech alkaline silica sols provide potassium-, low-sodium- and ammonium-stabilized aqueous nanosilica options. Grade selection should begin with the permitted counter-ion and alkali limit, then confirm concentration, particle size and pH.
| Model | Stabilization | SiO₂ Content | Particle Size | Published Alkali Limit | pH | Shelf Life |
|---|---|---|---|---|---|---|
| P3010 | Potassium | 30±1% | 10–20 nm | K₂O ≤0.3% | 9–10 | ≥12 months |
| LA3010A | Low sodium | 30±1% | 10–20 nm | Na₂O ≤0.01% | 8–10 | ≥12 months |
| LA3010B | Low sodium | 30±1% | 10–20 nm | Na₂O ≤0.05% | 8–10 | ≥12 months |
| LA3010C | Low sodium | 30±1% | 10–20 nm | Na₂O ≤0.1% | 8–10 | ≥12 months |
| AM3010 | Ammonium | 30±1% | 10–15 nm | Na₂O ≤0.1% | 8–10 | ≥12 months |
| AM4010 | Ammonium | 40±1% | 10–15 nm | Na₂O ≤0.1% | 8–10 | ≥12 months |
| AM4020 | Ammonium | 40±1% | 20–30 nm | Na₂O ≤0.1% | 8–10 | ≥12 months |
Published alkali values refer to different chemical bases. Na₂O and K₂O values should not be compared as though they were the same counter-ion specification. Confirm the analytical basis before ordering.
Choose the Counter-Ion Before the Solids Level

AM4010 and AM4020
Provide 40±1% SiO₂ with either 10–15 nm or 20–30 nm particle-size ranges.
Confirm Alkaline Sol Compatibility Under Process Conditions
Similar pH values do not make alkaline silica sols interchangeable. Counter-ion chemistry, ionic strength and other formulation components can change dispersion stability and finished performance.
- Counter-ion: specify potassium, low-sodium, ammonium or another permitted stabilization system.
- Alkali limit: state the required Na₂O, K₂O or element-specific limit and analytical method.
- Core parameters: provide SiO₂ content, particle size, pH, density and viscosity.
- Formulation components: list salts, acids, binders, pigments, surfactants, solvents and process water.
- Processing conditions: provide addition order, dilution, shear, temperature, drying and curing conditions.
- Stability criteria: define acceptable viscosity change, gelation, settling and storage period.
- Order details: include sample quantity, annual demand, packaging and destination country.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and protect from freezing. Freezing can cause irreversible gelation.
Direct Sunlight
Avoid prolonged exposure to direct sunlight during storage and transportation.
Container Closure
Keep containers closed to limit evaporation, contamination and precipitation of silica particles.
Alkaline Silica Sol Purchasing Questions
What is alkaline silica sol?
It is an aqueous dispersion of amorphous silica nanoparticles stabilized within an alkaline pH range using an appropriate counter-ion system.
Which alkaline stabilization systems are listed?
The representative range includes potassium-, low-sodium- and ammonium-stabilized silica sols.
Which grade has the lowest published sodium limit?
LA3010A has a published Na₂O limit of ≤0.01%, compared with ≤0.05% for LA3010B and ≤0.1% for LA3010C.
Are different alkaline silica sols interchangeable?
No. Counter-ion chemistry, alkali content, particle size, concentration, pH and formulation compatibility must be evaluated together.
How should alkaline silica sol be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container securely closed.

Applications of Alkaline Silica Sol
The suitable alkaline silica sol depends on counter-ion chemistry, alkali limit, particle size, concentration and compatibility with the complete process formulation.
Water-Based Coatings
Selected grades can be evaluated as inorganic nanosilica components in compatible alkaline coating and surface-treatment systems.
Inorganic Binder Systems
Alkaline sols may be assessed for bonding and network formation in compatible ceramic, mineral and refractory formulations.
Paper Surface Treatments
Low-sodium or alternative-counter-ion grades can be tested in compatible paper coating and receptive-layer formulations.
Textile Processing
Selected alkaline grades may be qualified with compatible sizing polymers, starches and textile auxiliaries.
Catalyst Carrier Preparation
Controlled-alkali grades can be evaluated as silica sources or binders where counter-ion and impurity limits are defined.
Custom Alkaline Formulations
Application trials can be designed around the required stabilizer, ionic environment, pH, solids content and stability criteria.
