Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

High-Purity Hydrophobic Fumed Silica (SiO TWO)

Premium Nano Colloidal Silica for Advanced Applications

This item is a high-purity type of silicon dioxide (SiO TWO), used advanced fumed silica innovation. It features a hydrophobic surface area, which suggests it fends off water successfully. The product appears as a fine, free-flowing white powder with excellent dispersion residential or commercial properties.

The silica particles are nano-sized and have a large area. This gives the item solid thickening, anti-settling, and enhancing capabilities. It works well in systems where moisture resistance is important. Common uses consist of coverings, adhesives, sealers, cosmetics, and specialized chemicals.

Key Features:
– Exceptionally high purity (≥ 99.8% SiO TWO).
– Hydrophobic surface area treatment for water resistance.
– Regular bit size in the nanometer variety.
– Reduced dampness material and exceptional flowability.
– Chemically inert and thermally stable.

Producers pick this silica due to the fact that it boosts item performance without impacting clearness or shade. It mixes smoothly right into natural systems and aids control viscosity even at low enhancement rates. The hydrophobic nature avoids clumping in humid atmospheres and makes sure lasting stability in solutions.

Technical Highlights:
– Specific surface area: 150– 400 m ²/ g.
– Mass density: 30– 80 g/L.
– pH (in diffusion): near neutral.
– Loss on drying out: less than 1.0%.

This fumed silica meets stringent quality standards for industrial and consumer applications. Each set goes through rigorous testing to assure uniformity in purity, bit framework, and surface properties.

Applications of Oxide Silice Sio2 Hydrophobic Fumed Silica ( Silicon Dioxide ) High Purity Nano Colloidal Silica / Silica Sol

Applications of High-Purity Hydrophobic Fumed Silica (SiO TWO)

Coatings and Paints

Hydrophobic fumed silica enhances scratch resistance and toughness in paints and industrial finishings. It stops wetness from going into the surface area. This maintains the coating strong gradually. The material additionally stops pigments from settling throughout storage space. That indicates users get a regular mix each time they open up the container.

Adhesives and Sealants

In adhesives and sealers, this silica functions as a thickening representative. It provides much better control during application. The item remains where you put it. It does not run or trickle. At the same time, it adds strength to the final bond. Water can not weaken the joint due to the fact that the silica wards off wetness.

Electronic Devices and Accuracy Spreading

High-purity nano colloidal silica is utilized in electronics manufacturing. It aids create smooth, even layers on circuit boards. In financial investment spreading, it develops secure ceramic coverings around steel parts. These shells hold their shape at high temperatures. They escape easily after casting.

Sprucing up and Abrasives

Silica sol works well in accuracy polishing compounds. It eliminates tiny flaws without damaging fragile surface areas. Glass, silicon wafers, and optical lenses all benefit from this mild action. The bits are uniform in dimension. That ensures a consistent coating each time.

Personal Treatment and Pharmaceuticals

Due to the fact that it is pure and safe, hydrophobic fumed silica appears in some cosmetics and medications. It takes in oil on the skin. It likewise assists powders flow freely. In tablets, it protects against clumping and enhances security. The body does not absorb it, so it goes through safely.

This product fulfills stringent high quality criteria. It contains extremely few contaminations. That makes it appropriate for sensitive applications where performance and security issue most.

5 FAQs of Oxide Silice Sio2 Hydrophobic Fumed Silica ( Silicon Dioxide ) High Purity Nano Colloidal Silica / Silica Sol

What is Oxide Silice SiO₂ Hydrophobic Fumed Silica?

Oxide Silice SiO₂ Hydrophobic Fumed Silica is a high-purity form of silicon dioxide made through flame hydrolysis. Its particles are nano-sized and treated to repel water. This makes it ideal for applications where moisture resistance matters.

How does hydrophobic fumed silica differ from regular silica?

Regular fumed silica attracts water. Hydrophobic fumed silica has a surface coating that pushes water away. This treatment changes how it mixes with other materials. It works better in non-polar systems like oils, resins, and organic solvents.

Where is this material commonly used?

This silica is used in many industries. You’ll find it in paints, coatings, adhesives, sealants, and cosmetics. It helps thicken liquids, prevent settling, and improve texture. Because it resists water, it also boosts product stability in humid conditions.

Is high-purity nano colloidal silica the same as fumed silica?

No. High-purity nano colloidal silica, or silica sol, is a liquid suspension of silica nanoparticles in water. Fumed silica is a dry powder made at high temperatures. Both are pure SiO₂, but their forms and uses differ. Colloidal silica suits applications needing even dispersion in water-based systems.

Why choose high-purity grades?

High purity means fewer impurities like metals or salts. This is important in electronics, pharmaceuticals, and precision coatings. Impurities can hurt performance or cause defects. Using high-purity SiO₂ ensures consistent results and meets strict industry standards.
