Small Particle Colloidal Silica Grade Comparison
| Model | Particle Size | SiO₂ Content | Na₂O Content | pH | Shelf Life |
|---|---|---|---|---|---|
| SS1505 | 3–5 nm | 15±1% | ≤0.5% | 10–11 | ≥12 months |
| SS3010 | 6–9 nm | 30±1% | ≤0.5% | 10–11 | ≥12 months |
| SS3015 | 10–15 nm | 30±1% | ≤0.5% | 10–11 | ≥12 months |
Published standard parameters are shown above. Confirm the target particle-size range, silica content and final acceptance limits before sampling or ordering.
Select by Particle Size and Silica Content
SS1505
The smallest published particle-size grade, with a standard SiO₂ content of 15±1%.
SS3010
A fine-particle grade with 30±1% SiO₂, Na₂O ≤0.5% and pH 10–11.
SS3015
The largest standard particle-size range in the SS series, with 30±1% SiO₂.
Confirm by Sample
Compare particle size and silica content under the buyer's actual processing conditions before bulk approval.
Information Needed for Grade Recommendation
The SS grades differ by particle size and silica concentration. Confirm both values together with the required analytical and purchasing conditions.
- Particle size: specify 3–5 nm, 6–9 nm or 10–15 nm.
- Silica content: confirm 15±1% or 30±1% SiO₂.
- Sodium limit: confirm that Na₂O ≤0.5% meets the purchasing specification.
- Required pH: confirm compatibility with the standard pH range of 10–11.
- Quality requirements: provide the test method, certificate requirements and acceptance limits.
- Order details: include trial 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 limit water evaporation and precipitation of solid silica particles.

Applications of Small Particle Colloidal Silica
Small particle colloidal silica is used in selected catalyst-carrier, specialty-coating and high-temperature binder formulations. Select the grade by particle size and silica concentration, then verify compatibility under actual processing conditions.
Catalyst Carriers
Evaluated as a fine silica source or inorganic binder in compatible catalyst-carrier preparation processes.
Specialty Coatings
Used as a nanoscale silica component in coating formulations requiring small, controlled particles.
High-Temperature Binders
Suitable for formulation trials requiring an inorganic silica binder under elevated-temperature conditions.
Ceramic Materials
Can be assessed as a fine-particle binder or functional silica component in compatible ceramic systems.
Surface Treatment
Evaluated in compatible surface-modification formulations requiring particles as small as 3–5 nm.
Functional Inorganic Materials
Supports material-development projects requiring a choice of fine particle size and silica concentration.
