Powder&Beads

Particle and beads aerogels offer a range of potential applications, namely:

  • multipactor suppression using dielectric filling techniques;
  • hydrocarbons absorption.

 

These aerogels are nanoporous structures with properties such as such as:

  • high hydrophobicity;
  • high surface area;
  • high electrical insulation.
