Applications: Due to its unique properties, nano silica finds applications in a wide range of fields including electronics, optics, biomedicine, and construction materials.

Features of nano silica

High Surface Area: One of the standout features of nano silica is its extremely high surface area relative to volume, which makes it highly reactive and useful for catalysis.

Enhanced Mechanical Properties: When added to other materials, nano silica can significantly improve mechanical strength, durability, and wear resistance.

Optical Properties: Depending on their size and shape, nano silica particles can manipulate light in interesting ways, making them useful in optical devices.

Biocompatibility: In biomedical applications, certain forms of nano silica are known for their biocompatibility and ability to deliver drugs within the body effectively.

Thermal Stability: Nano silica exhibits excellent thermal stability, allowing it to maintain its structure and properties at high temperatures.

Specification of 99%-99.999% purity Fumed Silicon oxide Silica SiO2 nano powder

This fumed silicon oxide powder, also called silica or SiO2 nano powder, offers high purity levels. You can get it from 99% pure up to 99.999% pure. The higher purity grades are for demanding uses. The material appears as a fluffy white powder. It feels very light and flows easily. The particles are incredibly small. Primary particles range from about 5 to 50 nanometers. These tiny particles stick together. They form larger aggregates. These aggregates are typically 100 to 500 nanometers. This small size gives the powder a huge surface area. The surface area is usually between 50 and 400 square meters per gram. This large surface makes it very reactive. It interacts strongly with other materials.

The powder has low bulk density. It packs loosely. The density is around 0.03 to 0.1 grams per cubic centimeter. The true density of solid silica is higher. It’s about 2.2 grams per cubic centimeter. This powder is chemically stable. It doesn’t dissolve in water. Acids don’t affect it much either, except strong hydrofluoric acid. It shows good thermal stability. It handles high temperatures well. Its melting point is over 1600 degrees Celsius. The powder is non-toxic and safe to handle normally. Use proper ventilation to avoid breathing dust.

Different purity levels suit different needs. The 99% grade works well for rubbers and plastics. It reinforces these materials. It makes tires stronger. It thickens paints and coatings. The 99.9% purity is better for silicones. It improves sealants and adhesives. It acts as a thickener. The highest purity, 99.999%, is for electronics and optics. It’s used in semiconductors. It’s used in optical fibers. It’s used in special ceramics. It’s even used in some cosmetics and pharmaceuticals. The nano size and purity determine its function. Choose the right grade for your application. This powder is a versatile material. Its properties make it useful across many industries.

Applications of 99%-99.999% purity Fumed Silicon oxide Silica SiO2 nano powder

Fumed silica powder is extremely fine silicon dioxide. Its purity matters for different jobs. High purity silica does many important things. This powder comes in several purity grades. Each grade fits specific industry needs.

99% pure silica is very common. It works well in industrial products. Manufacturers add it to paints and coatings. It makes these thicker and stronger. The powder helps control how liquids flow. Sealants and adhesives use this grade. It prevents sagging before curing. Builders rely on this property. Rubber compounds get reinforced with it. Tires become more durable. This silica acts as a free-flow agent. It stops powders from clumping together. Food processing sometimes uses it carefully.

Higher purity levels like 99.9% offer more specialized performance. This silica is cleaner. Electronics manufacturing needs this. It goes into thin films and insulating layers. These layers are critical for microchips. Pharmaceutical companies choose high purity silica. It acts as a carrier for medicines. The powder helps pills flow smoothly during production. Cosmetics use it for texture. Lotions feel smoother. High-end paints achieve better gloss and stability. This silica prevents settling in liquids.

The highest purity, 99.999%, is ultra-clean. Only the most sensitive applications require it. Semiconductor fabrication uses this grade. It polishes silicon wafers perfectly. Any tiny impurity ruins microchips. Advanced optics need this purity. It makes lenses and coatings clearer. Scientific research often specifies this level. Experiments demand absolute material consistency. Fiber optic cables use it for signal clarity.

5 FAQs of 99%-99.999% purity Fumed Silicon oxide Silica SiO2 nano powder

What is fumed silicon oxide (SiO2) nano powder?
It’s a very fine white powder. We make it by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates tiny particles. These particles fuse into branched chains. The result is a powder with extremely small particles. The typical size is nanometers. This gives it unique properties.

Why does purity matter? 99% to 99.999% is a big range.
High purity means fewer unwanted elements. Elements like metals or salts are impurities. Lower purity (99%) might be okay for some jobs. Higher purity (99.999%) is critical for advanced uses. Electronics and optics need ultra-pure material. Impurities can ruin performance. Think about semiconductors or special glass. Pure silica works better.

Where is this high-purity fumed silica used?
It goes into many high-tech products. Electronics use it for chip polishing slurries. Battery makers add it to improve performance. Specialty coatings use it for hardness or clarity. Advanced adhesives and sealants get stronger with it. Pharmaceutical tablets use it as a flow agent. High-purity grades are essential for optical fibers and lenses.

Is it safe to handle?
You need care. The tiny particles float easily in air. Breathing them in isn’t good. Always use gloves and safety glasses. Work in a place with good airflow, like a fume hood. Don’t let the dust get into the air. Check the safety sheet for specific instructions. Follow all handling rules.

How should I store this nano powder?
Keep it dry. Moisture makes it clump. Seal the container tightly after opening. Store it in a cool, dry place. Avoid big temperature changes. Keep it away from strong acids or bases. Keep it away from things that could contaminate it. Proper storage keeps it working right.
