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.

5 FAQs of Fumed Silica Nano Silica Powder Silicon Dioxide silicon dioxide SiO2 Hydrophobic Fumed Silica

What is hydrophobic fumed silica? Hydrophobic fumed silica is a fine powder made of silicon dioxide (SiO2). It is treated to repel water. This treatment changes its surface properties. The powder is lightweight. It has high purity. It is used to improve material performance in many industries.

How is hydrophobic fumed silica produced? The process starts with vaporizing silicon tetrachloride. The vapor is burned in a hydrogen-oxygen flame. This creates tiny silica particles. These particles form chain-like structures. The surface is then treated with silane agents. This makes it water-resistant. The result is a fine, fluffy powder.

What industries use hydrophobic fumed silica? It is common in coatings, adhesives, and sealants. It acts as a thickener. It prevents sagging in paints. It improves durability in rubber products. It stabilizes cosmetics like lotions. It controls powder flow in pharmaceuticals. It is also used in electronics for insulation.

Why pick hydrophobic over regular fumed silica? Hydrophobic silica repels moisture. This is critical for water-sensitive applications. It prevents clumping in humid conditions. It improves compatibility with non-polar materials like oils. It offers better dispersion in organic systems. It reduces curing time in resins.

Is hydrophobic fumed silica safe to handle? It is generally safe with proper precautions. Avoid breathing the dust. Use gloves and masks during handling. Store it in a dry, ventilated area. Keep it away from sparks or open flames. Follow local regulations for disposal. Check safety data sheets for specific guidance.
