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.

5 FAQs of Provide Sample Nano Silica Aerogel Powder with 2~40um Particle Size

Frequently Asked Questions About Nano Silica Aerogel Powder (2–40 µm)

What is nano silica aerogel powder?

Nano silica aerogel powder is a lightweight, highly porous material made from silica. Its particles range from 2 to 40 micrometers in size. This powder has very low density and excellent thermal insulation properties. It is often used in construction, aerospace, and industrial applications where heat resistance matters.

Why choose this particle size range?

The 2–40 µm size offers a good balance between flowability and surface area. Smaller particles fill gaps better, while larger ones help with handling and mixing. This range works well in coatings, composites, and insulation systems without clogging or clumping.

Is the powder safe to handle?

Yes, but basic safety steps are needed. Wear gloves, eye protection, and a dust mask when working with fine powders. The material itself is non-toxic, but like any fine dust, it can irritate the lungs or skin if inhaled or touched directly for long periods.

How should I store the powder?

Keep it in a sealed container away from moisture. Silica aerogel absorbs water easily, which can reduce its performance. Store it in a cool, dry place. Make sure the packaging stays closed when not in use.

Can I get a sample before placing a large order?

Yes. We provide sample quantities so you can test the powder in your specific application. This helps you check compatibility, performance, and handling before committing to bulk purchase. Just contact our team to request a sample.
