Aerogel powder is a powder-like material obtained by processing aerogel through specific techniques. It has an extremely high porosity, ranging from 80% to 99.8%, and contains a large number of nanoscale pores and nanoscale solid frameworks inside. This makes its density extremely low and enables it to bring special properties to the material system without adding too much weight.
Description
Due to its unique nano-porous structure, it greatly suppresses the convective heat transfer of gases and has an extremely low thermal conductivity. It is one of the solid materials with the best known heat insulation performance at present. The specific surface area can typically reach 500-1000 m²/g, providing a broad interface for chemical reactions, adsorption and other processes, and has significant advantages in fields such as catalysis and adsorption. Generally, it has good chemical stability and can resist the erosion of acids, alkalis and other chemical substances within a certain range. For example, silica aerogel powder can maintain a stable structure and performance in neutral and weakly acidic or alkaline environments. With its high specific surface area and porous structure, it has a strong adsorption capacity for liquid and gas molecules, and can be used to adsorb heavy metal ions, organic pollutants in water, as well as harmful gases in the air. Aerogel powder can be compounded with various materials, such as fibers and polymers, to produce composite materials of different forms and properties, to meet the application requirements of different fields, such as aerogel felt and aerogel coatings.
