1. a method for preparing the low density silica aerogel fast is characterized in that said method comprises the steps:

  • SiO is provided 2Hydrogel;

    To said SiO 2Hydrogel carries out microwave exposure, makes it reach complete gelation;

    With polar solvent and non-polar solvent the hydrogel of resulting complete gelation is carried out solvent exchange successively;

    Obtain the low density silica aerogel.
