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 High Quality 5 um SiO2 Aerogel Powder CAS No. 7631-86-9 Silica Aerogel

Frequently Asked Questions About High-Quality 5 µm SiO₂ Aerogel Powder (CAS No. 7631-86-9)

What is silica aerogel powder?

Silica aerogel powder is a lightweight, porous material made from silicon dioxide (SiO₂). It has a particle size of about 5 micrometers and is known for its extremely low density and high surface area. This powder form offers the same thermal insulation properties as solid aerogels but is easier to mix into coatings, composites, or other materials.

Why choose 5 µm particle size?

The 5 µm size strikes a balance between handling safety and performance. Smaller particles can be harder to manage and may pose inhalation risks. Larger particles might not disperse evenly. The 5 µm size flows well, mixes smoothly, and maintains the aerogel’s insulating structure without compromising ease of use.

What are the main uses of this powder?

This powder is used in thermal insulation paints, fire-resistant coatings, aerospace components, and specialty plastics. It also works in oil absorption, catalyst supports, and personal care products. Its nanostructure traps air, which reduces heat transfer and improves energy efficiency in many applications.

Is it safe to handle?

Yes, when proper precautions are followed. Wear gloves, eye protection, and a dust mask during handling. Avoid creating airborne dust. Store in a dry, sealed container away from moisture. The powder itself is non-toxic, but like any fine particulate, it should not be inhaled.

How should it be stored?

Keep the powder in an airtight container in a cool, dry place. Silica aerogel absorbs moisture easily, which can reduce its effectiveness. Make sure the packaging stays sealed when not in use. Do not store near strong acids, bases, or oxidizing agents.
