Ammonia Stabilized Silica Sol Grade Comparison
Peak-tech AM grades are alkaline aqueous nanosilica dispersions using an ammonium stabilization direction. Standard options provide two SiO₂ concentrations and two particle-size ranges for industrial formulation trials.
| 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 can be reviewed for customization. Confirm the required nominal size, tolerance, test method and complete specification before sampling.
Terminology note: "Ammonia stabilized" is used here as a search term for an ammonium-stabilized silica-sol system. It does not define a guaranteed free-ammonia, NH₄⁺ or volatile-content value. Request and confirm those limits separately when they are critical.
Choose by Solids Level and Particle Size
AM3010
Standard 30% option with 10–15 nm particles, Na₂O ≤0.1% and a published pH range of 8–10.
AM4010
Increases supplied SiO₂ content to 40±1% while retaining the 10–15 nm particle-size range.
AM4020
Combines 40±1% SiO₂ with a 20–30 nm particle band for a different surface-area and packing profile.
Particle-Size Adjustment
A custom particle target can be assessed after the measurement method, tolerance, quantity and application are provided.
Confirm Ammonium-System Requirements Before Testing
Specify both the silica-sol parameters and any ammonia- or ammonium-related process limits. Similar particle size and pH do not guarantee equivalent behavior.
- Core specification: provide SiO₂ content, particle size, pH, density and viscosity.
- Ammonium requirement: state any free-ammonia, NH₄⁺, odor, volatile or residual-content limits and test methods.
- Sodium limit: confirm whether the published Na₂O limit of ≤0.1% is acceptable.
- Process environment: list acids, salts, binders, catalysts, pigments, solvents and process water.
- Handling conditions: provide ventilation, temperature, mixing order, dilution and drying or curing conditions.
- Acceptance criteria: define storage stability and the relevant coating, bonding, polishing or finished-product tests.
- 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.
Closed and Ventilated Handling
Keep containers closed and follow site-specific ventilation and chemical-handling requirements during transfer and use.
Ammonia Stabilized Silica Sol Purchasing Questions
Which ammonia stabilized silica sol grades are available?
The standard ammonium-stabilized AM grades are AM3010, AM4010 and AM4020.
Does ammonia stabilized define the free-ammonia content?
No. The term describes the stabilization direction. Free-ammonia, ammonium-ion and volatile-content limits must be specified and confirmed separately.
How do AM3010 and AM4010 differ?
Both use a 10–15 nm particle range. AM3010 contains 30±1% SiO₂, while AM4010 contains 40±1%.
Which grade has the larger standard particle size?
AM4020 has a published particle-size range of 20–30 nm, compared with 10–15 nm for AM3010 and AM4010.
How should ammonia stabilized silica sol be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, keep the container closed, and follow the applicable ventilation and handling requirements.

Applications of Ammonia Stabilized Silica Sol
The appropriate AM grade depends on solids content, particle size, ammonia or ammonium limits, sodium limit and compatibility with the complete process formulation.
Catalyst and Carrier Preparation
Evaluate ammonium-stabilized grades as silica sources or inorganic binders under the actual mixing, drying and calcination conditions.
Electronic Material Systems
Candidate grades can be assessed where ammonium stabilization, controlled sodium and defined particle size are purchasing requirements.
Precision Polishing
Test selectable particle sizes and solids levels for removal behavior, surface finish, stability and defect performance.
Specialty Coatings
Evaluate compatibility, storage stability, drying response and film properties in water-compatible coating formulations.
Ceramic and Refractory Binders
Selected grades may be tested for penetration, bonding, drying and thermal compatibility in inorganic systems.
Custom Low-Sodium Processes
Application trials can be designed around ammonium chemistry, sodium limits, volatile requirements and process-specific acceptance tests.
