Ammonium Colloidal Silica Grade Comparison
| Model | SiO₂ Content | Particle Size | Na₂O Content | pH | Shelf Life |
|---|---|---|---|---|---|
| AM3010 | 30±1% | 10–15 nm | ≤0.1% | 8–10 | ≥12 months |
| AM4010 | 40±1% | 10–15 nm | ≤0.1% | 8–10 | ≥12 months |
| AM4020 | 40±1% | 20–30 nm | ≤0.1% | 8–10 | ≥12 months |
Particle size is customizable. Confirm the target range and final specification limits before sampling or ordering.
Select by Silica Content and Particle Size
AM3010
Ammonium colloidal silica with 10–15 nm particles, Na₂O ≤0.1% and pH 8–10.
AM4010
Higher-solids grade retaining the 10–15 nm particle-size range of AM3010.
AM4020
Higher-solids grade with a larger standard particle-size range than AM4010.
Particle Size
A customized particle-size target can be reviewed after the required value, tolerance and order conditions are provided.
Information Needed for Grade Recommendation
AM3010, AM4010 and AM4020 provide two standard silica concentrations and two particle-size ranges. Confirm the required specification before selecting a grade.
- Silica content: specify 30±1% or 40±1% SiO₂.
- Particle size: select 10–15 nm, 20–30 nm or provide a customized target.
- Sodium limit: confirm that Na₂O ≤0.1% meets the purchasing specification.
- Required pH: confirm compatibility with the standard pH range of 8–10.
- 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.
