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 99%-99.999% Purity Fumed Silicon Oxide Silica Sio2 Nano Powder

Fumed silicon oxide (SiO2) nano powder is a high-purity material used in many industries. Here are five common questions about it. What is fumed silica nano powder? It’s a fine white powder made by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates tiny particles with high surface area. The purity ranges from 99% to 99.999%, making it suitable for sensitive applications.

What applications use this material? It’s added to coatings, adhesives, and sealants to improve strength and thickness. In pharmaceuticals, it helps control drug release. Electronics manufacturers use it as an insulator. The high purity ensures minimal contamination in products like semiconductors.

Is fumed silica safe to handle? The powder is non-toxic but requires care. Inhalation can irritate the lungs. Wear gloves and masks when handling it. Store it in sealed containers to avoid moisture absorption. Follow safety guidelines from the supplier.

How does particle size affect performance? Smaller particles increase surface area, boosting reactivity. Most grades have particles between 5-50 nanometers. Finer powders mix better in liquids. Larger particles might settle faster. Choose the size based on your process needs.

What storage conditions are needed? Keep the powder dry and cool. Moisture causes clumping. Use airtight containers made of plastic or coated metal. Avoid direct sunlight. Check the expiration date—high-purity grades degrade faster if stored poorly.

Why choose 99.999% purity over lower grades? Ultra-pure silica reduces impurities in final products. This matters for electronics or medical devices. Lower grades work for less critical uses like paints. Confirm purity requirements with your application standards.

How is quality tested? Suppliers use X-ray diffraction and BET surface area analysis. These methods check crystal structure and particle size. Ask for a certificate of analysis. Reputable suppliers provide batch-specific data.

Can it replace other silica types? Sometimes. Fumed silica has unique properties like low density and high porosity. Precipitated silica is cheaper but less pure. Test compatibility before switching materials.

What’s the typical shelf life? Unopened containers last two years. Once opened, use it within six months. Exposure to humidity shortens usability. Buy smaller quantities if you use it slowly.

Does temperature affect performance? Extreme heat or cold can change particle structure. Most grades handle up to 120°C. Check the datasheet for thermal limits. Store in a climate-controlled area if possible.
