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 Silica Aerogel with Excellent Thermal Insulation Performance

**What is hydrophobic silica aerogel?** Hydrophobic silica aerogel is a lightweight, porous material derived from silica, known for its exceptional thermal insulation properties. Its nanostructure consists of over 90% air, trapped in a network of silica nanoparticles, which minimizes heat transfer. The “hydrophobic” feature comes from a chemical treatment that repels water, preventing moisture absorption and maintaining performance in humid environments.

**Why does hydrophobic silica aerogel have excellent thermal insulation?** The material’s ultra-low thermal conductivity (as low as 0.015 W/m·K) stems from its nanostructure, which restricts heat transfer via conduction, convection, and radiation. The tiny pores hinder air molecule movement, reducing conductive heat, while the silica matrix blocks infrared radiation. This combination makes it one of the most effective insulating materials available.

**How does the hydrophobic property benefit thermal insulation?** Moisture absorption can degrade insulation performance and material integrity. Hydrophobic silica aerogel repels water, ensuring it remains dry and maintains its thermal efficiency even in high-humidity conditions. This also prevents mold growth, corrosion, or structural damage, extending the material’s lifespan in applications like building insulation or underwater pipelines.

**Where is hydrophobic silica aerogel commonly used?** It’s ideal for high-performance insulation in extreme environments. Applications include building insulation (walls, roofs), industrial pipelines, aerospace components, and outdoor apparel. Its lightweight nature and flexibility also make it suitable for retrofitting existing structures or insulating irregular surfaces without adding significant weight.

**Is hydrophobic silica aerogel safe to handle?** While non-toxic and chemically stable, handling requires precautions. The dry powder form can generate dust, which may irritate the respiratory system—use gloves and masks during installation. Pre-engineered forms like blankets or panels minimize dust exposure. Avoid direct ingestion or prolonged skin contact. Properly installed, it poses no health risks and remains stable under temperatures ranging from -200°C to 650°C.
