Solubilità
Silica is poorly soluble in water. The solubility is higher for the amorphous form compared to the crystalline compound.

Applicazioni

Silica is used in the manufacture of glass for windows, drinking glasses, beverage bottles, and many other materials. Optical fibers for telecommunication are made from silica. It is also used as a raw material for many ceramics such as earthenware, stoneware, and porcelain. In addition, silica is a common additive in the production of foods and pharmaceutical products.

Note

It is a very stable compound of silicon.
