Aerogel Particles

Aerogel Particles Manufacturer
Aerogel particles mostly semi-transparent and extremely light in weight. It is also known as "solid smoke" or "frozen smoke". The density of common silica aerogel is approximately 0.2 grams per cubic centimeter, which is only one fifth of that of water. It is one of the lightest solids in the world and currently has the lowest thermal conductivity among all solid and porous materials. Its heat transfer coefficient is much lower than that of still air, usually only about half of that of still air. Many aerogels have super hydrophobicity, high water repellency and low water absorption rate. Its porous structure gives it an exceptionally large specific surface area, making it an ideal material for adsorbing pollutants in water. It has a significant hindering effect on the speed of sound wave propagation.

Key Features of Aerogel particles
1. Appearance: Translucent, extremely lightweight, often referred to as solid smoke or frozen smoke.

2. Density: Typical silica aerogel particles have a density of around 0.2 g/cm³, about one-fifth that of water.

3. Porosity: 80%-99.8%, providing a highly porous structure.

4. Specific Surface Area: Very high, making them ideal for adsorption and filtration applications.

5. Thermal Conductivity: Extremely low, far below that of still air, offering excellent insulation.

6. Hydrophobicity: Many particles are highly water-repellent, preventing moisture absorption.

7.Acoustic Performance: The porous structure helps reduce sound transmission.
