Development of low density silica aerogel as a capture medium for hyper-velocity particles
The objective of this study is to develop micro-porous silica aerogel glass with optimal properties for its potential use as a capture medium of hyper-velocity particles. The important properties for this application are identified as ultra-low bulk density (i.e. < 0.1 gm/cc), high transparency to visible light, and purity (absence of organic and inorganic contaminants). Our approach is to expand on our existing knowledge and experience concerning sol-gel chemistry and the extraction technology which we now use to routinely produce clear silica aerogel monoliths at densities higher than 0.1 gm/cc. We expect to push the existing technology toward ultra-low density aerogels and identify any limitations impeding the development of this material with optimal properties for the particle capture application. 3 refs., 10 figs.
