Silica Sol for Industrial Formulation and Processing
Silica sol is a stable aqueous dispersion of nanoscale amorphous silicon dioxide particles. Peak-tech supplies acidic, neutral, alkaline, sodium-, ammonium- and potassium-stabilized, high-purity and modified grades for applications requiring inorganic binding, surface reinforcement, controlled polishing or functional particle behavior.
| Core Property | Peak-tech Family Range | Selection Importance | Confirm for Each Grade |
|---|---|---|---|
| SiO₂ Content | 20–40 wt% | Delivered silica, water load and dosage | Nominal value and tolerance |
| Particle Size | 3–180 nm | Surface area, packing, binding and polishing | Method and distribution |
| pH | 2.0–10.5 | Stability and formulation compatibility | Specified pH window |
| Stabilization | Multiple ionic and modified systems | Charge, impurity profile and process fit | Ion and surface chemistry |
| Packaging | 25 kg, 250 kg and 1000 kg | Trial, production and bulk handling | Availability and shipment plan |
These values describe the wider product family. They are not simultaneous specifications for one silica-sol grade. Confirm the feasible combination before ordering.
Choose the Silica Sol Chemistry
For Controlled Acidic Formulations
Acidic silica sol supports formulations where alkaline stabilizers are unsuitable and compatibility must be maintained within a lower pH window.
For Sensitive Compatibility Requirements
Near-neutral, cationic or surface-modified directions can be evaluated for fibers, coatings, batteries and specialized interfaces.
For General Industrial Processing
Alkaline grades are widely evaluated in casting, refractory, cement, coatings and other water-based industrial systems.
For Contamination-Sensitive Uses
Low-sodium and high-purity directions support electronics, catalysts, batteries, CMP and other applications with controlled impurities.
Match the Grade to the Process
- Define the function: inorganic binding, reinforcement, particle packing, polishing, carrier structure or surface modification.
- Set particle requirements: specify target size, distribution and morphology according to application performance.
- Balance solids and water: select SiO₂ content with reference to viscosity, drying, dilution and delivered-solids economics.
- Confirm pH and stabilizer: review every binder, pigment, salt, catalyst, surfactant, substrate and process-water condition.
- Specify purity: provide numerical sodium, metal-ion and element-specific limits with analytical methods.
- Reproduce the process: test addition order, shear, temperature, hold time, drying, curing, firing or polishing conditions.
- Define the purchase: include sample quantity, annual demand, packaging, required documents and destination country.

Keep Containers Sealed
Prevent evaporation, contamination, crusting and unintended changes in solids or pH during storage and dispensing.
Protect from Freezing
Freezing can cause irreversible particle precipitation or gelation. Follow the grade-specific storage range.
Use Clean Equipment
Dedicated pumps, hoses and fittings reduce contamination by salts, acids, alkalis or multivalent ions.
Trial Before Scale-Up
Validate colloidal stability, process behavior and final performance in the complete formulation before bulk use.
Silica Sol Purchasing Questions
What is silica sol?
Silica sol is a stable aqueous colloidal dispersion of nanoscale amorphous SiO₂ particles used for binding, reinforcement, polishing, catalyst support and surface modification.
Is silica sol the same as colloidal silica?
In industrial usage, the terms are commonly used for the same type of water-based nanosilica dispersion.
Which silica sol grade should I choose?
Choose by application, particle size, solids, pH, stabilizer, purity and formulation compatibility. Test the grade in the actual process.
Can silica sol be diluted with water?
Yes, using compatible water and a validated procedure. Hardness, salts, pH and addition sequence can destabilize the dispersion.
How should silica sol be stored?
Keep it sealed, prevent freezing, avoid contamination and prolonged direct sunlight, and follow the selected grade's TDS and label.
