Solubility equilibrium exists between dissolved (monomeric) and amorphous silica. For the hot springs that were studied, the solubility is about 315 p.p.m. at 90°C and 110 p.p.m. at 25°C, which is very similar to Krauskopf's experimental data. Monomeric silica polymerizes so slowly to ...

Webpected that activated silica will make the process less critical. The point of silica addition must also be studied. In some waters the silica should be added ahead of the alum, and, in others, subsequent to it. The proper point must be determined for each water. At present, however, it appears that silica application usually follows alum addition. WebThe 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.
