Industrial Grade Silica Sol Specifications
Peak-tech industrial grade silica sol is an aqueous dispersion of amorphous nano silica developed for binding, surface reinforcement, polishing, coating and process-aid applications. Grades are selected by particle size, solids content, pH, stabilizing ion and purity requirement.
| Grade Direction | SiO₂ Content | Particle Size | pH Range | Typical Function | Typical Application |
|---|---|---|---|---|---|
| Fine-Particle Grade | 20–40 wt%* | 3–20 nm | Grade dependent | High surface activity | Catalyst support, CMP, functional coatings |
| General Industrial Grade | 20–40 wt%* | 20–100 nm | Grade dependent | Balanced binding and handling | Coatings, paper, textile and cement |
| Large-Particle Grade | 20–40 wt%* | 100–180 nm | Grade dependent | Packing and thermal network | Casting, refractory and hard coatings |
*The displayed values describe the broader industrial product-family envelope. They are not simultaneous specifications for one grade. Available Peak-tech systems include acidic, alkaline, sodium-, ammonium-, potassium-stabilized and modified silica sols; the exact combination must be confirmed before ordering.
Why Formulators Use Silica Sol
Build a Silica Network
Silica particles form Si–O–Si bonding during drying or curing, supporting strength, adhesion and heat-resistant inorganic structures.
Improve Hardness and Wear Resistance
Nanoscale silica can reinforce surfaces and contribute to scratch resistance, abrasion resistance and durability in compatible formulations.
Match Surface Area and Packing
Particle size influences reactivity, packing density, pore structure, polishing behavior and interaction with other ingredients.
Integrate into Aqueous Processes
The liquid dispersion supports metering, dilution and mixing in suitable water-based industrial production systems.
Information Required for a Technical Recommendation
"Industrial grade" covers multiple chemistries and applications. A useful recommendation requires the process conditions and acceptance criteria, not only a generic product name.
- Application: identify casting, refractory, coating, catalyst, paper, textile, cement, polishing or another process.
- Target specification: state SiO₂ content, particle size, pH, density, viscosity and stabilizing-ion preference.
- Formulation compatibility: list binders, pigments, salts, catalysts, surfactants, solvents and other additives.
- Process conditions: provide dilution water, mixing order, shear, temperature, drying or firing conditions and residence time.
- Performance target: define bonding strength, hardness, porosity, removal rate, coating quality or other measurable criteria.
- Commercial details: include sample quantity, expected annual consumption, packaging preference and destination country.

Industrial Grade Silica Sol Questions
What is industrial grade silica sol?
It is a stable aqueous dispersion of amorphous silica particles selected for industrial functions such as inorganic binding, reinforcement, polishing, coating or process assistance.
Which particle size should an industrial buyer select?
Fine particles generally provide higher surface activity, while larger particles can support packing, permeability or thermal-network requirements. Selection must be validated in the actual process.
Are acidic and alkaline industrial grades available?
Yes. Peak-tech offers acidic, alkaline and different ion-stabilized or modified product directions. Compatibility with the complete formulation should be confirmed before sampling.
Can one grade combine every value shown in the table?
No. The table presents a product-family range. Particle size, solids, pH, stabilizer and viscosity must be matched as a feasible grade combination.
Should industrial silica sol be trialed before bulk ordering?
Yes. A controlled trial helps verify stability, compatibility, dosing, processing behavior and the final performance target before scale-up.

Industrial Uses of Silica Sol
The suitable grade depends on the required binding, surface, particle-packing or processing function. Application trials should reproduce the actual formulation and operating conditions.
Investment Casting
Used as an inorganic binder in ceramic-shell systems where slurry stability, shell strength, permeability and firing behavior must be balanced.
Refractory Products
Supports low-VOC inorganic bonding and heat-resistant networks in compatible refractory mixes, coatings and shaped-product processes.
Industrial Coatings
Can contribute to adhesion, surface hardness, abrasion resistance and heat resistance in properly formulated water-based coatings.
Catalyst Supports
Provides a silica framework and surface area for carrier or binder systems where pore structure and chemical compatibility are controlled.
Polishing Processes
Controlled particles can be evaluated for CMP, optical glass, ceramic and other precision-polishing formulations requiring consistent surface results.
Paper, Textile and Cement
Selected grades serve as formulation aids, surface-treatment components or inorganic modifiers in paper, textile, cement and concrete processes.
