Nano Silica Sol Particle-Size Bands
Nano silica sol is an aqueous dispersion of amorphous silica nanoparticles. Particle size, distribution, solids content and stabilizing chemistry can be selected to match surface interaction, packing behavior and process compatibility.
| Customization Band | Particle Size | Published Size Control | SiO₂ Content | Physical Form |
|---|---|---|---|---|
| Fine Nano Sol | 3–20 nm | ±1 nm below 20 nm | 20–40 wt% | Aqueous dispersion |
| Intermediate Nano Sol | 20–100 nm | ±5 nm above 20 nm | 20–40 wt% | Aqueous dispersion |
| Large Nano Sol | 100–180 nm | ±5 nm above 20 nm | 20–40 wt% | Aqueous dispersion |
These are customization bands, not fixed model codes. Confirm the nominal particle size, distribution, measurement method, silica content, pH and stabilization chemistry before requesting a sample.
Choose the Particle Band by Process Function
Higher Surface Interaction
Fine particles provide higher relative specific surface area and stronger interfacial interaction at equivalent silica loading.
Balanced Flow and Packing
Intermediate particles provide a configurable balance between surface activity, dispersion handling and particle packing.
Lower Relative Surface Area
Larger particles offer different packing and surface-interaction behavior for compatible formulations and polishing systems.
Match pH and Stabilizer
Particle size must be paired with a compatible pH, counter-ion, solids level and process electrolyte environment.
Information Needed for Nano Silica Sol Selection
A nominal particle diameter is not a complete purchasing specification. Define the reporting method and the liquid formulation requirements together.
- Particle specification: provide nominal size, acceptable distribution and tolerance.
- Measurement method: state the instrument, calculation model and sample-preparation procedure.
- Liquid chemistry: specify pH, stabilizing ion, SiO₂ content, density and viscosity.
- Purity limits: identify sodium, total metal-ion or element-specific requirements.
- Process compatibility: list binders, pigments, catalysts, salts, solvents, process water and mixing conditions.
- Performance test: describe the application trial, acceptance limits and required certificate data.
- 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. Temperatures below 0°C can cause irreversible gelation.
Direct Sunlight
Avoid prolonged exposure to direct sunlight during storage and transportation.
Container Closure
Keep containers closed to reduce water evaporation, contamination and precipitation of solid silica particles.
Nano Silica Sol Purchasing Questions
What is nano silica sol?
Nano silica sol is a stable aqueous dispersion of nanoscale amorphous silica particles. It is supplied as a liquid rather than a dry nanosilica powder.
What particle-size range can be customized?
The published customization envelope covers 3–180 nm, divided into fine, intermediate and large nano-particle bands.
What particle-size control is published?
Published control is ±1 nm for sizes below 20 nm and ±5 nm for sizes above 20 nm, subject to the agreed measurement method.
Why is the measurement method important?
Different instruments, calculation models and sample-preparation procedures can produce different reported values for the same dispersion.
How should nano silica sol be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container securely closed.

Applications of Nano Silica Sol
Application performance depends on particle size and distribution, silica concentration, stabilizing chemistry, purity and compatibility with the buyer's actual process.
Precision Polishing
Controlled particle-size sols can be qualified for compatible glass, ceramic, metal and semiconductor surface-finishing processes.
Functional Coatings
Fine aqueous silica dispersions may be evaluated for surface modification, hardness and inorganic network formation.
Catalyst Carrier Preparation
Selected fine-particle and low-impurity grades can be assessed as silica sources or binders in carrier manufacturing.
Ceramic and Refractory Binders
Appropriate particle bands may be evaluated for packing, bonding and thermal-process compatibility.
Paper and Textile Treatments
Nano silica sols can be tested in compatible receptive coatings, sizing systems and surface-treatment formulations.
Concrete and Mineral Systems
Selected grades may be assessed as reactive nanosilica dispersions in compatible cementitious and mineral formulations.
