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 Fumed Silicon oxide / Silica / SiO2 nano powder

Fumed silica powder is an artificial nanomaterial made from silicon and oxygen. It’s additionally called silicon dioxide or SiO2 nano powder. This white powder has very tiny bits. The primary fragment size is commonly about 15 nanometers. These tiny bits stick creating bigger accumulations. The aggregate dimension typically drops in between 100 and 500 nanometers. This framework gives fumed silica distinct residential or commercial properties.

The surface area is really high. Specific surface often varies from 50 to 400 square meters per gram. High surface area means solid surface task. This makes the powder really valuable. Fumed silica is primarily pure silicon dioxide. Pureness levels are usually above 99.8%. It includes extremely low levels of steels and various other impurities. This high purity is essential for delicate applications.

The powder is chemically inert. It doesn’t react quickly with various other substances. It’s also very stable thermally. Fumed silica can withstand heats. Its melting factor mores than 1600 degrees Celsius. The powder has low bulk thickness. It really feels very light and fluffy. The tap thickness is usually between 30 and 60 grams per liter.

Fumed silica is available in different kinds. Some kinds are hydrophilic. They draw in water. Other types are hydrophobic. They fend off water. Hydrophobic qualities are treated with special agents. This treatment modifications just how the powder engages with liquids.

This nano powder is an effective reinforcing agent. It makes products more powerful. It thickens fluids effectively. It avoids working out in suspensions. It regulates the flow of liquids and pastes. You find it in lots of items. It’s used in silicone rubber, adhesives, sealers, paints, finishes, inks, cosmetics, pharmaceuticals, and food. Its little dimension and high surface area are key to its efficiency.

Applications of Fumed Silicon oxide / Silica / SiO2 nano powder

Fumed silica powder includes exceptionally small bits. These bits are really light and fluffy. They have special residential properties making them useful in numerous products. Industries depend on this material for different jobs.

Rubber and plastic makers add fumed silica. It makes tires stronger and last longer. It assists cars and truck components resist warmth and wear. Silicone sealants use it too. It makes caulks and gaskets tougher and extra flexible.

Paint and layer firms use it. It stops fluids from dripping. It makes surfaces thicker and simpler to use. It assists surfaces completely dry smooth. Inks and printer toners require it to flow correctly and print clearly.

Daily items include fumed silica. Toothpaste uses it for mild cleansing. It aids gloss teeth without scratching. Cosmetics like powders and foundations rely upon it. It stops clumping and soaks up oil. It makes make-up feel smooth on skin.

Food and medicine utilize special qualities. It maintains powders like seasonings and consume mixes moving easily. It quits them from sticking in the container. Drug pills often use it. It aids control just how quick medicine liquifies.

Unique applications exist. Fumed silica thickens liquid materials. This is important for compounds in watercrafts or airplane. Electronics use ultra-pure types. It works as insulation in some components. Research study explores brand-new battery and solar cell layouts. Scientists see possible for much better energy storage space.

5 FAQs of Fumed Silicon oxide / Silica / SiO2 nano powder

Here are 5 FAQs about Fumed Silica (SiO2 Nano Powder):

What is fumed silica?
Fumed silica is an ultra-fine powder. We make it by burning silicon tetrachloride vapor in a hydrogen-oxygen flame. This process creates tiny particles. These particles fuse into branched chains. The result is a very light powder with high surface area. It looks like fluffy white fluff.

Why is particle size important?
Particle size matters a lot. Smaller particles mean more surface area. More surface area means the powder interacts better with other materials. This improves thickening. It improves reinforcement. It improves anti-settling properties. Fine particles create better performance in many applications.

How does purity affect my product?
Purity is critical. High-purity fumed silica has fewer impurities. Impurities can cause unwanted reactions. They can change the color of your final product. They can weaken performance. Choose a grade matching your purity needs. This ensures consistent results.

Is fumed silica safe to handle?
Handle it carefully. The fine dust can be a breathing hazard. Always use proper ventilation. Wear a dust mask. Wear safety glasses. Wear gloves. Avoid skin contact. Avoid breathing the dust. Follow the safety data sheet (SDS) instructions exactly.

How should I store this powder?
Keep it dry. Store it in a cool place. Keep it sealed tightly in its original container. Moisture makes fumed silica clump together. Clumping makes it hard to use. It can ruin the powder’s special properties. Protect it from humidity.
