When of crystalline origin, silica is insoluble in water and in organic solvents. The kind of silica most handled in the industrial environment is fumed silica. Its bulk density is between 0.16 and 0.19 g / cm³. We can also mention perlite, which constitutes a siliceous sand of volcanic origin, and has a high water retention capacity.
