Silica gel is a rigid three-dimensional network of colloidal silica and is classified as aquagel (pores are filled with water), xerogel (aqueous phase in the pores is removed by evaporation), or aerogel (solvent is removed by supercritical extraction), depending on how they are made (Kalapathy et al., 2000). From: Rice Bran and Rice Bran Oil, 2019
