Description
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 Pyrogenic Silica CAS 7631-86-9 Fumed Silica 200
What is Pyrogenic Silica CAS 7631-86-9?
It’s a very fine, white powder. We make it by burning silicon tetrachloride in a hydrogen-oxygen flame. This high heat creates tiny particles of silica. The CAS number 7631-86-9 is its unique chemical identifier. This number confirms the substance.
What does Fumed Silica 200 do?
It acts like a thickener. It makes liquids thicker or more viscous. It also stops things from settling. It makes powders flow better. It reinforces materials. It controls how liquids flow. You find it in paints, coatings, adhesives, sealants, and many other products. It improves their performance.
Where is Fumed Silica 200 typically used?
It is common in industrial applications. Paints and coatings use it for anti-settling and thickening. Adhesives and sealants use it for reinforcement and sag control. Pharmaceuticals use it in tablets. Food uses it as an anti-caking agent. Personal care items like toothpaste use it for thickening. It works in silicone rubber too.
How is Fumed Silica different from Precipitated Silica?
The production method is different. Fumed silica uses a flame process. Precipitated silica uses a wet chemical process. This difference affects the particles. Fumed silica particles are smaller. They form chain-like aggregates. This gives fumed silica higher purity. It offers better thickening power. It provides superior reinforcement. It often has lower moisture too.
Is Fumed Silica 200 safe to handle?
Always follow safety guidelines. It is generally considered safe for its intended uses. Handle it carefully to avoid dust. Breathing in dust can irritate lungs. Wear appropriate protective gear. This includes dust masks and eye protection. Refer to the product’s Safety Data Sheet (SDS). The SDS gives complete handling and safety instructions.
