Silicone aerogel is a new material with extremely low density and high porosity, showcasing revolutionary application potential in multiple fields due to its ultra-lightweight, ultra-low thermal conductivity, and excellent mechanical properties. This article will explore the characteristics, preparation methods, and innovative applications of silicone aerogel in construction, aerospace, and energy fields.

Silicone aerogel is a porous material formed by the sol-gel method using silicone resin, with a porosity of over 99% and a density as low as 0.003 g/cm³, making it one of the lightest solid materials known. At the same time, its nano-scale porous structure gives it an extremely low thermal conductivity (as low as 0.015 W/m·K), making it one of the best-performing thermal insulation materials.
In the construction field, silicone aerogel is widely used in wall insulation, roof thermal insulation, and energy-efficient windows. Compared with traditional insulation materials, its ultra-lightweight properties significantly reduce the load on buildings, while its excellent thermal insulation performance greatly improves energy efficiency, making it an important component of green buildings.
Although silicone aerogel has excellent performance, its high production cost has been the main bottleneck restricting its large-scale application. In recent years, with the development of green production processes and breakthroughs in large-scale production technology, its cost has gradually decreased, and its application scope has increasingly expanded.

In summary, silicone aerogel, with its unique performance advantages, is driving its revolutionary applications in fields such as construction, aerospace, and energy.
