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 Silicone Nano SiO2 Silicon Dioxide Amorphous Silica 99.8% 15nm Hydrophilic Fumed Silica

Frequently Asked Questions

What is hydrophilic fumed silica?

Hydrophilic fumed silica is a fine white powder made from amorphous silicon dioxide (SiO₂). It has a particle size of about 15 nanometers and a purity level of 99.8%. This type of silica attracts water, which makes it mix well in water-based systems.

How is this silica produced?

It is made through a high-temperature flame hydrolysis process. Silicon tetrachloride vapor is burned in a hydrogen-oxygen flame. This creates pure, nano-sized silica particles that form loose, chain-like structures. The result is a very light and fluffy powder with strong thickening power.

What are the main uses?

This silica works as a thickener, anti-settling agent, and flow controller. You will find it in paints, coatings, adhesives, sealants, cosmetics, and some food-grade applications. It helps keep solid particles evenly spread and stops liquids from separating over time.

Why choose 15nm particle size?

Smaller particles like 15nm give more surface area per gram. That means better performance at lower doses. It thickens more efficiently, improves stability, and gives smoother texture in final products compared to larger-particle silica.

Is it safe to handle?

Yes, but you must follow basic safety steps. Wear gloves, eye protection, and a dust mask when handling the dry powder. Though non-toxic, fine powders can irritate lungs or eyes if inhaled or touched directly. Store in a dry place away from moisture to keep its performance stable.
