Production of hollow aerogel microspheres

摘要

A method is described for making hollow aerogel microspheres of 800-1200 mu diameter and 100-300 mu wall thickness by forming hollow alcogel microspheres during the sol/gel process in a catalytic atmosphere and capturing them on a foam surface containing catalyst. Supercritical drying of the formed hollow alcogel microspheres yields hollow aerogel microspheres which are suitable for ICF targets.
