Overview of Silica aerogel

Definition: Silica aerogel is a solid material derived from a gel, in which the liquid component of the gel has been replaced with a gas. This process results in a material that retains its gel-like structure but is extremely lightweight.

Production: It is typically produced through a sol-gel process followed by supercritical drying, which removes the liquid without causing the solid structure to collapse.

Applications: Commonly used in aerospace applications, as insulation in buildings, pipelines, and oil and gas industries due to its remarkable insulative properties.

Features of Silica aerogel

Low Density: One of the lightest solid materials known, often lighter than air, giving it a ghostly appearance.

Thermal Insulation: Possesses extremely low thermal conductivity, making it an excellent insulator even at high temperatures.

Transparency: Depending on its thickness and processing, silica aerogels can be highly transparent, allowing them to be used in certain optical applications.

Hydrophobicity: Many types of silica aerogels are treated to become hydrophobic, which helps prevent moisture absorption and enhances their durability and insulation performance.

Mechanical Fragility: Despite its impressive properties, silica aerogel is quite brittle and requires careful handling to avoid damage.

Specification of silicon dioxide silica fume Factory whole fumed silica equitable aerogel fumed silica powder

This silica fume factory produces high-purity silicon dioxide powder. We make several key types: silica fume, whole fumed silica, and aerogel fumed silica powder. Each serves specific industrial needs.

Silica fume is a very fine powder. It’s a by-product from silicon metal production. Its particles are extremely small. This gives it a large surface area. Silica fume is mostly amorphous silicon dioxide. It has high purity. Typical SiO2 content exceeds 90%. It reacts strongly with cement. This makes concrete much stronger and more durable. It reduces permeability significantly. It improves resistance to chemicals. It enhances abrasion resistance.

Whole fumed silica is manufactured directly. We burn silicon tetrachloride in a flame. This creates pure, synthetic amorphous silica. The particles are nano-sized. They form chain-like aggregates. This powder has remarkable thickening power. It controls viscosity very well. It acts as a reinforcing filler. It prevents caking. It is free-flowing. It is chemically inert. Major uses include silicone rubber, adhesives, sealants, paints, and coatings. It improves texture and stability.

Aerogel fumed silica powder is a special form. It is ultra-lightweight. It has an extremely porous structure. The density is very low. It provides outstanding thermal insulation. It is highly effective. It is hydrophobic. This means it repels water. It maintains performance in humid conditions. It finds use in advanced insulation materials, energy-efficient systems, and specialized composites.

Key specifications apply across our products. Purity is critical. We ensure consistent SiO2 content. Particle size distribution is tightly controlled. Surface area is a vital property. We measure it precisely. Loss on ignition indicates moisture and impurities. We keep it low. pH value affects compatibility. We test it carefully. Bulk density influences handling. We optimize it for different applications. Performance in the final product is our focus.

Applications of silicon dioxide silica fume Factory whole fumed silica equitable aerogel fumed silica powder

Silicon dioxide appears in many forms with important uses. Silica fume comes from factories making silicon metal or ferrosilicon alloys. This fine powder works well in concrete. It makes concrete stronger and more durable. Silica fume fills tiny spaces between cement particles. This action creates a denser concrete mix. Denser concrete stops water and chemicals getting in. This protection helps concrete last longer in tough places like bridges or marine structures.

Fumed silica is another key silicon dioxide product. Factories make it by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates very pure, extremely fine particles. The particles have a huge surface area. This property gives fumed silica unique abilities. It thickens liquids effectively. You find it thickening paints, coatings, adhesives, and sealants. It stops liquids from separating or sagging. Fumed silica also acts as a free-flow agent. It prevents powders like food ingredients or medicines from clumping.

Aerogel fumed silica powder takes things further. It involves a special drying process applied to a silica gel. This removes the liquid without collapsing the gel structure. The result is an incredibly light solid full of air pockets. Aerogel fumed silica powder is a fantastic insulator. It blocks heat transfer extremely well. This makes it valuable for insulating pipes, buildings, and even scientific equipment. Its low density and high porosity are key advantages. Aerogels also find roles in filtration systems and specialized chemical applications.

5 FAQs of silicon dioxide silica fume Factory whole fumed silica equitable aerogel fumed silica powder

Here are 5 common questions about our factory’s fumed silica products:

What is fumed silica powder? Fumed silica powder is a very fine, white powder. We make it from silicon dioxide (SiO2). We use a special high-temperature flame process. This process creates tiny, pure particles. These particles have unique properties.

How is fumed silica different from silica fume? People sometimes confuse these names. Silica fume is a by-product. It comes from making silicon metal or ferrosilicon alloys. Our fumed silica is different. We make it on purpose in a controlled factory process. Our fumed silica has a much smaller particle size. It is also much purer. This makes it suitable for demanding uses.

What are the main uses for fumed silica? Fumed silica is incredibly useful. It acts as a thickener. It prevents settling. It reinforces materials. You find it in many things. It’s in paints, coatings, sealants, adhesives, silicone rubber, cosmetics, and pharmaceuticals. It improves flow. It adds strength. It controls viscosity.

Is fumed silica aerogel the same thing? Fumed silica aerogel is a special form. It uses our fumed silica powder as a base material. We process it further. We remove the liquid very carefully. This creates an ultra-lightweight solid structure. It has extremely low density. It has very high surface area. It has excellent insulating properties. It’s used in high-tech insulation, energy systems, and scientific applications.

Is fumed silica safe to handle? Our fumed silica powder is non-toxic. It is chemically inert. You must handle it carefully. Breathing in fine dust is not good. Always use proper personal protective equipment (PPE). This includes things like dust masks and gloves. Follow good industrial hygiene practices in your workplace. Check the Safety Data Sheet (SDS) for specific handling instructions.
