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 Nano Silica Powder White Microsilica Powder Micro Silica Fume

Nano silica powder is also called microsilica or silica fume. It is a very fine powder. This powder is made mostly of silicon dioxide. The silicon dioxide content is usually over 85%. The particles are extremely small. The average particle size is often less than 1 micrometer. That means it is a nanomaterial. It looks like a white or grey powder. It feels smooth and dry to the touch. This powder is very useful in many industries.

Builders use it a lot in concrete. Adding nano silica to concrete makes the concrete much stronger. It also makes the concrete more durable. The concrete lasts longer. It helps fill tiny spaces in the concrete mix. This makes the concrete denser. Denser concrete resists water and chemicals better. The concrete doesn’t crack as easily. It is good for bridges, tunnels, and tall buildings.

It works well in other materials too. People use it in ceramics and refractories. It improves the strength and heat resistance of these products. Paint and coating makers use it too. It helps paints stick better to surfaces. It makes the paint coating tougher. It can act as a thickener. It helps control how the paint flows.

This powder has other benefits. It has a very large surface area. This large surface area helps it react easily. It promotes chemical reactions. It acts as a filler. It improves the properties of plastics and rubber. It makes them stronger and more stable.

It comes packaged for easy handling. You usually get it in sealed bags. Common sizes are 500kg or 1000kg bags. It might come in smaller containers too. Always store it in a dry place. Keep it away from moisture. Moisture can make it clump together. Handle it carefully. Avoid breathing in the dust. Use a mask when handling it.

Applications of Nano Silica Powder White Microsilica Powder Micro Silica Fume

Nano silica powder, also known as white microsilica powder or micro silica fume, is a very fine material. It is made of very small silica particles. Its small size gives it special qualities. These qualities make it useful in many industries. Builders use it a lot. They add it to concrete and cement. It makes concrete much stronger and tougher. It also helps concrete last longer. Concrete gets less porous. Water cannot get inside as easily. This protects the steel inside concrete from rusting. Concrete becomes more resistant to chemicals too. This is important for buildings and roads. Factories use it in fireproof materials. These materials need to handle very high heat. Adding nano silica makes them more stable. It helps them keep their shape under heat. This is vital for furnaces and kilns. Ceramic makers use nano silica. It makes ceramics denser and smoother. The surface finish improves. Glazes and coatings stick better. This leads to better-looking and stronger ceramic items. The chemical industry relies on it. It acts as a thickener in liquids. It helps control how liquids flow. It prevents settling in mixtures. Paint and adhesive makers use it for this reason. Electronics manufacturers need it too. It polishes silicon wafers very finely. This is a key step in making computer chips. Clean surfaces are essential. It is also used in special coatings. These coatings protect electronic parts. Environmental uses are growing. Nano silica helps capture pollutants. It traps harmful substances in filters. It aids in cleaning up contaminated soil. Its small size helps it react well. This makes treatment processes more effective.

5 FAQs of Nano Silica Powder White Microsilica Powder Micro Silica Fume

Nano silica powder is also called microsilica or silica fume. It is a very fine powder. It comes from producing silicon metal or ferrosilicon alloys. It is mostly silicon dioxide. This powder is incredibly small. Its particles are much tinier than cement particles. This makes it useful in many industries.

What is nano silica powder used for?
Its main use is in concrete and cement products. Adding microsilica to concrete improves it greatly. It makes the concrete stronger and more durable. It also makes the concrete less permeable. This means water and chemicals struggle to pass through. Builders use it in high-performance concrete, like bridges or tall buildings. It is also used in refractories, ceramics, and sometimes plastics.

Why add microsilica to concrete?
Adding microsilica gives concrete big benefits. It fills the tiny gaps between cement particles. This creates a much denser concrete structure. The dense structure boosts strength and toughness. It also greatly reduces permeability. This helps the concrete resist damage from chemicals and freezing. It also improves the bond between the concrete and steel reinforcement.

Is nano silica powder safe?
Handling silica fume needs care. It is a very fine dust. Breathing in any fine dust is not good for your lungs. Always wear the right protective gear. Use a mask and gloves when handling the powder. Work in well-ventilated areas. Follow all safety instructions from the supplier.

How do you handle and store nano silica powder?
Store microsilica powder in a cool, dry place. Keep it away from moisture. Moisture makes the powder clump together. It can become difficult to use. The powder usually comes in sealed bags or special containers. Keep the bags closed tightly when not in use. Handle the bags gently to avoid tearing and spills.
