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.

Specification of of Industrial-grade Nano-micron Silica High-purity Ultra-fine Hydrophilic Fumed Silica

This industrial-grade nano-micron silica is high-purity, ultra-fine, hydrophilic fumed silica. It meets demanding industrial standards. The primary component is silicon dioxide (SiO₂). Purity consistently exceeds 99.8%. This ensures minimal contamination. Particle size is extremely small. It ranges from 7 to 40 nanometers (nm). This nano-scale size provides a very large surface area. The specific surface area (BET method) is high. It typically falls between 150 and 400 square meters per gram (m²/g). This large surface area is crucial for performance.

The product is hydrophilic. This means it readily absorbs moisture from the air. It interacts well with water-based systems. Its surface chemistry is designed for strong interactions. It bonds effectively with many polymers and liquids. This improves reinforcement and thickening. It acts as a powerful rheology modifier. It controls flow and prevents sagging or settling. It enhances the stability of suspensions and pastes. It prevents particles from clumping together.

This fumed silica offers excellent reinforcement properties. It strengthens materials significantly. It increases the hardness and durability of composites. It improves abrasion resistance. It provides good thickening effects even at low concentrations. It is chemically inert under most conditions. It resists many acids and bases. It withstands high temperatures well. Its thermal stability is reliable. The powder appears white and fluffy. It has a very low bulk density. Handling requires care to avoid dust clouds.

The pH value of an aqueous suspension is important. It usually measures between 3.6 and 4.3. Loss on drying (LOI) is low. It is typically under 1.5% at 105°C. Loss on ignition (LOI) is also minimal. It is generally under 2.0% at 1000°C. This silica is packaged securely. Common options include 10kg or 20kg multi-ply paper bags. It also comes in larger bulk containers. Proper storage is essential. Keep it in a cool, dry place. Seal the container tightly after opening. This prevents moisture absorption before use.

5 FAQs of of Industrial-grade Nano-micron Silica High-purity Ultra-fine Hydrophilic Fumed Silica

What is industrial-grade nano-micron silica high-purity ultra-fine hydrophilic fumed silica?
It’s a special powder. It’s made by burning silicon tetrachloride in hydrogen-oxygen flames. This creates tiny particles. These particles are very small, measured in nanometers. The powder loves water. It’s very pure. It’s used in demanding industrial jobs.

Why is the “hydrophilic” part important?
Hydrophilic means water-loving. This silica attracts water molecules easily. It mixes well into water-based systems. It disperses evenly. This is key for many applications. Think coatings, adhesives, or sealants. It helps control thickness and flow. It prevents settling. It makes products stable.

How fine is “ultra-fine”?
Ultra-fine means extremely small particles. The particles are typically 7 to 40 nanometers wide. That’s much smaller than a human hair. This small size gives huge surface area. One gram can cover over 300 square meters. This large surface is powerful. It provides strong thickening, reinforcing, and anti-settling effects. Performance depends on this fineness.

What does “high-purity” mean here?
High-purity means very few impurities. The main part is silicon dioxide (SiO2). It’s over 99.8% pure. Harmful metals are very low. Chloride levels are also very low. This purity matters. It prevents unwanted reactions. It keeps the product’s color clear. It ensures consistent performance. It’s vital for sensitive applications like electronics or pharmaceuticals.
