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 Factory amorphous nano SiO2 20-50 nm silicon dioxide Fumed Silica

What is amorphous nano SiO₂ (20-50 nm)?
This is a very fine white powder. We make it using a special high-temperature flame process. This process creates silicon dioxide particles. These particles are extremely small, only 20 to 50 nanometers wide. They are not arranged in any crystal pattern. They are amorphous. This means the particles are randomly structured. This special structure gives the powder unique properties.

What are its key features?
This fumed silica has several important traits. It acts as a powerful thickener. It makes liquids like paints or gels thicker without changing them much. It is also a very good anti-settling agent. It stops solid particles in liquids from sinking to the bottom. It is extremely light and fluffy. It has a huge surface area for its tiny size. It resists high heat very well. It does not conduct electricity. It lets light pass through easily in many materials.

Where is this nano silica used?
You find it in many different products. It thickens paints, coatings, and printing inks. It prevents sagging. It acts as a reinforcing filler in silicone rubber. This makes the rubber stronger. It controls the flow in adhesives and sealants. It stops settling in liquid mixtures like resins. It improves texture in cosmetics like lotions. It prevents caking in powders. It helps control viscosity in many industrial processes.

Is this fumed silica safe?
Generally, yes, it is considered safe for its intended uses. Handle it carefully though. Avoid breathing in the fine dust. Use proper dust masks. Avoid getting it in your eyes. Wear safety glasses. Always follow the safety instructions on the product’s Material Safety Data Sheet (MSDS). Use good industrial hygiene practices.

Why is the 20-50 nm particle size important?
The tiny size is crucial for performance. Smaller particles have much more surface area. More surface area means the powder interacts better with liquids or other materials. This creates stronger thickening effects. It improves reinforcement in rubbers. It gives better stability against settling. The specific size range (20-50 nm) balances performance perfectly. It works very well. It is practical to handle and use in manufacturing.
