Large Particle Size Silica Sol Grade Comparison
Peak-tech LS silica sols provide defined large-particle intervals from 30–40 nm to 170–190 nm. Buyers can select the particle band first, then confirm solids content, pH, sodium limit and measurement method.
| Model | Particle Size | SiO₂ Content | Na₂O Content | Standard pH | Custom pH Range | Shelf Life |
|---|---|---|---|---|---|---|
| LS30 | 30–40 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS50 | 50–60 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS80 | 80–90 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS100 | 100–110 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS120 | 110–120 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS150 | 140–160 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
| LS180 | 170–190 nm | 30–50% | ≤0.4% | 9.5–10.5 | 3–11 | ≥12 months |
The 30–50% SiO₂ and pH 3–11 values describe the published customization envelope. Confirm the feasible combination, tolerance and analytical method for the selected LS grade.
Match the Particle Band to the Surface Process
LS30 and LS50
Smaller LS options for trials requiring more surface interaction than the higher-numbered large-particle grades.
LS80, LS100 and LS120
Intermediate large-particle bands for balancing contact mechanics, packing behavior and dispersion handling.
LS150 and LS180
The largest published LS options for processes requiring lower relative surface area and larger abrasive particles.
Custom Chemistry Review
pH adjustment must be evaluated together with particle stability, counter-ion requirements and other formulation ingredients.
Define Particle Distribution and Performance Together
A published particle interval is only the starting point. Large-particle silica sols should be approved using the actual process and surface-quality criteria.
- Particle-size band: select the LS grade and state nominal size, distribution and tolerance.
- Measurement method: identify the instrument, calculation model and sample-preparation procedure.
- Liquid specification: provide SiO₂ content, pH, sodium limit, density and viscosity.
- Process conditions: state mixing, dilution, flow rate, pressure, temperature and contact time.
- Surface requirements: define removal rate, roughness, scratch or defect limits and cleaning requirements where relevant.
- Stability criteria: specify acceptable settling, agglomeration, viscosity change 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 Management
Keep containers closed and confirm any agitation or recirculation procedure before long-term process use.
Large Particle Size Silica Sol Purchasing Questions
What large particle-size ranges are available?
The published LS intervals begin at 30–40 nm and extend through 170–190 nm across seven grades.
Which grade has the largest published particle range?
LS180 has the largest listed particle-size interval at 170–190 nm.
Can the pH and SiO₂ content be customized?
The published customization envelope is pH 3–11 and 30–50% SiO₂. The feasible combination must be confirmed for the selected particle-size grade.
Why must the particle-size method be specified?
Different instruments, calculation models and sample preparation can produce different reported values, affecting grade comparison and acceptance.
How should large particle silica sol be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container securely closed.
