What is Silica Aerogel?

Silica aerogel is a highly porous material created from silica gel. It has been dubbed “frozen smoke” due to its translucent appearance. The properties that make silica aerogel stand out include:

• Low Density: Typically, silica aerogels have densities as low as 1.0 kg/m³.
• High Surface Area: They possess a surface area ranging from 500 to 1000 m²/g, which contributes to their insulating properties.
• Thermal Conductivity: Silica aerogels exhibit extremely low thermal conductivity, usually between 0.013 and 0.020 W/m·K.

With advancements in technology, they are now formed into blankets, allowing for easy application in various scenarios.
