Ceramic Grade Colloidal Silica Comparison
| Model | Particle Size | SiO₂ Content | Grade Direction | pH | Shelf Life |
|---|---|---|---|---|---|
| LA3010A | 10–20 nm | 30±1% | Low sodium; Na₂O ≤0.01% | 8–10 | ≥12 months |
| AM3010 | 10–15 nm | 30±1% | Ammonium stabilized; Na₂O ≤0.1% | 8–10 | ≥12 months |
| P3010 | 10–20 nm | 30±1% | Potassium stabilized; K₂O ≤0.3% | 9–10 | ≥12 months |
| HC4010 | 10–15 nm | 40±1% | High solids; Na₂O ≤0.4% | 9.5–10.5 | ≥12 months |
"Ceramic grade" is not one universal specification. These representative candidates cover low-sodium, ammonium-stabilized, potassium-stabilized and higher-solids directions. Match the grade to the ceramic chemistry and process.
Select by Stabilizer, Alkali Limit and Solids
LA3010A Low-Sodium Candidate
LA3010A is the representative direction where sodium control is a critical requirement in the ceramic material specification.
AM3010 Process-Compatible Option
AM3010 provides 30±1% SiO₂ with 10–15 nm particles where ammonium stabilization is compatible with the formulation.
P3010 Alternative Alkali Direction
P3010 provides a potassium-stabilized 30±1% dispersion for systems where potassium is preferred over a sodium-based direction.
HC4010 Higher-Solids Candidate
HC4010 offers finer 10–15 nm particles at 40±1% SiO₂ where a higher supplied solids level is required.
Information Needed for Ceramic Grade Selection
Define the ceramic composition, impurity limits and processing conditions before choosing a stabilization direction.
- Ceramic composition: identify ceramic powders, fillers, dispersants, binders and other formulation components.
- Application: specify slurry casting, ceramic forming, coating, impregnation, bonding or another use.
- Chemical limits: provide the permitted sodium, potassium, ammonium and other critical impurity limits.
- Process targets: state rheology, green strength, drying rate, shrinkage, firing temperature, porosity and strength requirements.
- 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.
Ceramic Grade Colloidal Silica Questions
Which ceramic grade colloidal silica candidates are available?
Representative directions include low-sodium LA3010A, ammonium-stabilized AM3010, potassium-stabilized P3010 and higher-solids HC4010.
What defines a ceramic grade colloidal silica?
The required grade is defined by silica content, particle size, stabilization chemistry, pH, alkali limits and compatibility with the complete ceramic process.
Why does stabilization chemistry matter?
Sodium, potassium and ammonium directions can interact differently with ceramic powders, dispersants and thermal processing. The permitted ions should be specified before sampling.
Can particle size be customized?
Yes. Particle size is identified as customizable and should be confirmed with the target value, tolerance and test method.
How should ceramic grade colloidal silica be stored?
Store it at 0–40°C, prevent freezing and direct sunlight, and keep the container closed.

Applications of Ceramic Grade Colloidal Silica
Ceramic formulations may require different stabilization systems, alkali limits and silica concentrations. Select a representative grade only after the ceramic chemistry, forming process and thermal cycle are defined.
Low-Alkali Ceramic Systems
Low-sodium candidates can be evaluated where alkali-metal content forms part of the ceramic material specification.
Ammonium-Compatible Ceramics
Ammonium-stabilized grades can be assessed where that counter-ion direction matches the powder chemistry and thermal process.
Potassium-Compatible Ceramics
Potassium-stabilized colloidal silica can be tested where potassium is preferred over a conventional sodium-based system.
High-Solids Ceramic Binders
Higher-solids candidates can be evaluated where supplied silica loading and added process water must be balanced.
Technical and Porous Ceramics
Selected grades may be tested in oxide ceramics, porous bodies, filters and insulation materials under defined impurity limits.
Custom Ceramic Formulations
Supports qualification involving specific silica solids, particle size, pH, counter-ion chemistry and acceptance methods.
