Silica Physical Properties – nanoComposix
The density of silica nanoparticles is approximately 2 g/cm 3 and depends on the degree of condensation. Colloidal silica is amorphous or non-crystalline, meaning that the atoms do not have long-range order, similar to the atomic structure of bulk glass. As prepared, they are readily suspended in polar solvents such as water and ethanol.
