Overview of nano silica

Composition: Primarily composed of silicon dioxide (SiO2), similar to regular sand but on a much smaller scale.

Production: Nano silica can be produced through several methods such as sol-gel processes, vapor deposition, and plasma technology.

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 Hydrophilic/Hydrophobic Type Nano Silica Aerogel Powder, Airgel Particles

Hydrophilic and hydrophobic nano silica aerogel powders are advanced insulation materials. These powders consist of airgel particles. They look like fine, dry powders. The particles are very light. Density ranges from 0.060 g/cm³ to 0.100 g/cm³ typically. Particle sizes are small. Common sizes include 1-5 mm granules, 0.5-1 mm particles, and finer powders below 50 microns. Nanoscale pores create a sponge-like structure. This structure gives the powder a huge internal surface area. BET surface area often measures 600-800 m²/g. Porosity is extremely high, usually 85-98%. This means the material is mostly air.

The powder type matters. Hydrophilic powder absorbs water. Hydrophobic powder resists water absorption. The hydrophobic type repels water. This keeps performance stable in humid conditions. Both types offer very low thermal conductivity. Thermal conductivity values are typically 0.015-0.030 W/m·K at room temperature. This makes them excellent thermal insulators. They perform well across wide temperatures. Usable temperatures range from -200°C to 650°C, sometimes higher.

The powder is chemically stable. It is inert. Silica is the main component. It is non-toxic. It is non-flammable. This enhances safety. The powder appears white or slightly opaque. It feels dry and loose. Bulk density is low. This means large volumes are lightweight. Applications need this powder packed tightly. Compression fills voids between particles. This maximizes the insulation effect. Users handle the powder carefully. It generates minimal dust. The powder integrates into composites, coatings, or fills spaces directly. It provides efficient thermal barriers.

Applications of Hydrophilic/Hydrophobic Type Nano Silica Aerogel Powder, Airgel Particles

Nano silica aerogel powder is a special material. It is incredibly light. It has a very porous structure. This structure gives it unique abilities. Scientists make two main types: hydrophilic and hydrophobic. Each type has different uses. Hydrophilic powder loves water. Hydrophobic powder strongly repels water.

Hydrophobic silica aerogel powder is famous for insulation. Its tiny pores trap air extremely well. This stops heat from moving easily. Builders mix it into plasters and paints. This makes walls much warmer. Factories use it to insulate pipes and tanks. It saves energy. It works well in cold and hot places. Its water resistance is key. Moisture doesn’t ruin its insulating power. Clothing makers explore it too. It could make thinner, warmer jackets.

Hydrophilic silica aerogel powder acts differently. It attracts water molecules. This makes it useful in certain coatings. It can help control humidity. It finds a place in some cosmetic products. It helps manage texture and moisture. Scientists also use it in labs. It helps separate chemicals or absorb specific substances. Its high surface area is valuable here.

Both powders are very light. They add almost no weight. This is important for vehicles. Car and plane makers test them. They mix the powder into plastics or metals. The goal is stronger, lighter parts. Electronics is another area. The powder can insulate delicate circuits. It protects against heat and sometimes moisture. Hydrophobic types are best for moisture protection. Hydrophilic types serve different chemical roles. The small particle size lets it blend smoothly into many materials.

5 FAQs of Hydrophilic/Hydrophobic Type Nano Silica Aerogel Powder, Airgel Particles

This nano silica aerogel powder is incredibly lightweight. It has a very porous structure. This powder comes in two main types: hydrophilic and hydrophobic. Each type has specific uses.

What is nano silica aerogel powder?
It’s a super-light solid material. It’s made mostly of air trapped in a silica network. The powder feels dry. It looks like fine, white dust. Its structure has many tiny pores. This gives it unique properties.

Hydrophilic vs. Hydrophobic: What’s the difference?
Hydrophilic powder attracts water. It can absorb moisture easily. Hydrophobic powder repels water. Water beads up on its surface. The key difference is how each interacts with water. The hydrophobic type is treated to resist water.

Where is this aerogel powder used?
Hydrophilic powder is good for insulation needing moisture control. It works in certain building materials. Hydrophobic powder is better for insulation where moisture is a problem. It’s used in pipelines, roofs, and some clothing. Both types add thermal insulation.

What are the main benefits?
This powder provides excellent thermal insulation. It stops heat transfer very well. It’s extremely lightweight. It won’t add much weight to products. The porous structure creates these benefits. It works over a wide temperature range.

Is it safe to handle?
Wear gloves and a dust mask. Avoid breathing the fine dust. Keep it away from your eyes. Store it in a dry place. The powder itself is generally non-toxic. Proper handling prevents skin or eye irritation.
