Rice husk is a plentiful waste material in all rice growing areas. It is primarily disposed of by open burning, which is, of course, ecologically undesirable, although. Low density silica aerogel beads were synthesized from rice husk ash via sodium silicate route. The gel beads were prepared by the ball dropping method and. The present work describes an improved process for preparation of silica aerogel microparticles (SAMs) for drug delivery from rice husk ash.
