Aerogels possess low density, large surface area, and high porosity, as a result these are considered as the fascinating materials of the 21st century. Aerogel materials have a broad range of extraordinary properties and, therefore, have a remarkable number of applications. Several industrial applications of aerogels are under advance development, like particle detectors, catalysts, and thermal insulators. As the researchers realized their peculiar and extraordinary properties, newer applications of aerogels started emerging. There are technical and scientific applications, besides increasing industrial applications of aerogels. This chapter addresses the recent patents on aerogels.
