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 Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder

What is Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder? Hydrophobic SiO2 Silica Aerogel Powder is a lightweight, nanoporous material derived from silicon dioxide. It consists of a 3D network of silica nanoparticles with up to 99.8% air-filled pores, giving it ultra-low density and exceptional thermal insulation properties. Its hydrophobic nature comes from surface treatment with non-polar groups, making it water-repellent. This powder is ideal for applications requiring high thermal resistance without water absorption, such as construction, industrial coatings, or textiles.

Why is this aerogel powder hydrophobic? The hydrophobicity is achieved through a chemical modification process called silylation. During production, the silica surface is treated with hydrophobic agents like trimethylsilyl groups, which replace hydroxyl (-OH) groups on the aerogel’s surface. This creates a non-polar, water-resistant layer that prevents moisture absorption, ensuring the material maintains its insulation efficiency even in humid or wet environments.

How does it perform in thermal insulation? Silica aerogel powder has one of the lowest thermal conductivities (0.015–0.025 W/m·K) among solid materials, outperforming traditional insulators like fiberglass or foam. Its nanoporous structure minimizes heat transfer via conduction, convection, and radiation. It can withstand temperatures from -200°C to 650°C, making it suitable for extreme environments, such as pipelines, aerospace components, or high-temperature equipment.

What are the primary applications of this material? Common uses include thermal insulation coatings for buildings, energy-efficient windows, and industrial pipes. It’s also added to composites for lightweight insulation in aerospace or automotive sectors, incorporated into textiles for cold-weather gear, and used in oil and gas industries for subsea pipeline insulation. Its hydrophobic property makes it ideal for outdoor or moisture-prone settings.

Is it safe to handle? The powder is chemically inert and non-toxic but requires careful handling. Inhalation of fine particles may irritate the respiratory system, so use PPE like masks and gloves. Avoid direct skin contact to prevent dryness. Store in a sealed, dry environment to preserve its hydrophobic and insulating properties. Follow local regulations for disposal.
