Silica Aerogel Particles Description

Silica Aerogel, referred to as solid smoke, solid air, or blue smoke, is one of the lightest solid materials known, renowned for its exceptional thermal insulation properties. Composed of over 90% nano-sized pores and a three-dimensional silica nano-mesh structure, it provides superior thermal resistance while being extremely lightweight. In addition to its remarkable insulation performance, silica aerogel exhibits excellent light dispersion, high surface area, low density, and robust chemical stability, making it ideal for applications in aerospace, construction, energy, and advanced materials research.

FAQs

Are silica aerogel particles safe to handle?

Yes, they are generally safe to handle, but due to their light, powdery nature, it's recommended to wear protective gloves and a mask to avoid inhalation or skin irritation.

Are silica aerogel particles waterproof?

Standard silica aerogels are not inherently waterproof, but hydrophobic versions are available to resist moisture and maintain performance in damp environments.

What makes silica aerogel particles different from other insulation materials?

Their nano-porous structure provides unmatched thermal insulation, extremely low density, and high surface area, setting them apart from traditional insulators.
