Grade Selection

Select by Silica Content and Particle Size

30±1% SiO₂

AM3010

Ammonium colloidal silica with 10–15 nm particles, Na₂O ≤0.1% and pH 8–10.

40±1% SiO₂

AM4010

Higher-solids grade retaining the 10–15 nm particle-size range of AM3010.

20–30 nm

AM4020

Higher-solids grade with a larger standard particle-size range than AM4010.

Customizable

Particle Size

A customized particle-size target can be reviewed after the required value, tolerance and order conditions are provided.

Specification Confirmation

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 and Storage

Protect Product Stability During Storage

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.
