Low Sodium Colloidal Silica Grade Comparison
| Model | Na₂O Content | SiO₂ Content | Particle Size | pH | Shelf Life |
|---|---|---|---|---|---|
| LA3010A | ≤0.01% | 30±1% | 10–20 nm | 8–10 | ≥12 months |
| LA3010B | ≤0.05% | 30±1% | 10–20 nm | 8–10 | ≥12 months |
| LA3010C | ≤0.1% | 30±1% | 10–20 nm | 8–10 | ≥12 months |
Published standard parameters are shown above. Confirm the required sodium limit and final acceptance specification before sampling or ordering.
Select the Appropriate Sodium Limit
LA3010A
The lowest-sodium standard grade, with 30±1% SiO₂, 10–20 nm particles and pH 8–10.
LA3010B
An intermediate low-sodium grade for specifications that do not require the LA3010A sodium limit.
LA3010C
A standard low-sodium option sharing the same silica content, particle size and pH range.
Verify the Acceptance Method
Confirm the analytical method, sodium limit and certificate requirements before approving a grade for bulk supply.
Information Needed for Grade Recommendation
The three LA3010 grades differ mainly in their published Na₂O limits. Provide the required sodium specification and purchasing conditions so the correct grade can be confirmed.
- Sodium limit: specify ≤0.01%, ≤0.05% or ≤0.1% Na₂O.
- Silica content: confirm that 30±1% SiO₂ meets the specification.
- Particle size: confirm acceptance of the standard 10–20 nm range.
- Required pH: confirm compatibility with the standard pH range of 8–10.
- Testing requirements: provide the analytical method and certificate requirements.
- 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.
Low Sodium Colloidal Silica Purchasing Questions
Which low sodium colloidal silica grades are available?
The standard grades are LA3010A, LA3010B and LA3010C, with Na₂O limits of ≤0.01%, ≤0.05% and ≤0.1% respectively.
How do LA3010A, LA3010B and LA3010C differ?

Applications of Low Sodium Colloidal Silica
Low sodium colloidal silica can be evaluated where sodium content must be controlled without changing the standard silica concentration, particle size or alkaline pH range. Confirm compatibility under actual processing conditions before bulk use.
Electronic Materials
Evaluated in compatible material systems where tighter sodium limits help control alkali-metal contamination.
Precision Polishing
Suitable for polishing trials requiring controlled nanoscale silica and a defined low-sodium specification.
Catalyst Preparation
Can be assessed as a silica source or binder where sodium content affects catalyst composition or processing.
Specialty Coatings
Used in compatible coating formulations that require nanoscale silica with controlled sodium levels.
Ceramic Materials
Evaluated as an inorganic binder or silica component where alkali content is part of the material specification.
High-Purity Inorganic Binders
Suitable for development projects requiring a choice of three published Na₂O limits.
