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 99%-99.999% purity Fumed Silicon oxide Silica SiO2 nano powder

High-Purity Fumed Silica (SiO ₂) Nano Powder

Fumed silica, also called silicon dioxide (SiO TWO), is a high-performance nano powder made via fire hydrolysis. This process produces ultrafine, round fragments with exceptional purity and consistent high quality.

Purity Levels

Our fumed silica is readily available in multiple pureness qualities– ranging from 99% to 99.999%. These degrees fulfill rigorous sector requirements for electronics, pharmaceuticals, and progressed products. Higher pureness indicates fewer contaminations like metals or wetness, which is vital for sensitive applications.

Key Includes

The powder has an extremely high surface, usually in between 50 and 400 m TWO/ g. This offers it strong thickening, anti-settling, and strengthening buildings. Particles are amorphous, not crystalline, making them much safer and extra steady. The material is white, free-flowing, and odorless.

Typical Makes use of

Suppliers utilize this silica in numerous fields. In coverings and paints, it avoids pigment settling and boosts scrape resistance. In adhesives and sealants, it controls flow and includes stamina. In electronics, high-purity qualities function as insulators or fillers in semiconductors. The pharmaceutical sector uses it as a flow representative in tablet computers. It additionally appears in cosmetics, food additives, and specialty rubbers.

Handling and Storage space

Shop the powder in a completely dry, cool place far from wetness. Keep containers sealed when not being used. Though safe, avoid breathing fine dirt. Usage typical industrial hygiene techniques throughout handling.

Quality Assurance

Every set goes through rigorous testing. We verify particle size, surface, dampness content, and trace elements. Certifications of Analysis are given with each delivery to confirm purity and performance specifications.

5 FAQs of 99%-99.999% purity Fumed Silicon oxide Silica SiO2 nano powder

Frequently Asked Questions About High-Purity Fumed Silica (SiO₂) Nano Powder

What is fumed silica?

Fumed silica is a nano-sized powder made from silicon dioxide (SiO₂). It forms when silicon tetrachloride burns in a flame. The result is a very fine, white powder with high surface area and strong thickening power.

Why does purity matter?

Purity affects performance. Our fumed silica has 99% to 99.999% purity. This means almost no metal or other impurities are present. High purity ensures better stability, clarity, and function in sensitive applications like electronics or pharmaceuticals.

Where is this powder used?

This powder works in many industries. It thickens paints, prevents clumping in powders, strengthens rubber, and improves flow in cosmetics. In high-tech fields, it helps make coatings, adhesives, and battery materials more reliable.

How should I handle it?

Always wear gloves, eye protection, and a mask. The powder is very light and can become airborne easily. Store it in a dry, sealed container away from moisture. Keep it in a cool place to avoid clumping.

Is it safe?

Fumed silica is not classified as toxic. But like any fine dust, it can irritate the lungs if inhaled in large amounts. Use proper ventilation and follow safety guidelines. It is not meant for food or internal use unless specifically approved for that purpose.
