  Silicic acid - Wikipedia, the free encyclopedia
Silicic acid is a general name for a family of chemical compounds of silicon, hydrogen, and oxygen, with the general formula [SiO
Silicic acids may be formed by acidification of silicate salts (such as sodium silicate) in aqueous solution.
These algae polymerise the silicic acid to so-called biogenic silica, used to construct their cell walls (called frustules).

In micas, which are sheet silicates, the tetrahedra are joined to form continuous sheets that are stacked upon one another.
Framework silicates, such as feldspars and quartz, are based on three-dimensional frameworks of tetrahedra in which all oxygens are shared.
The crop of English hay is carefully weighed, the moisture calculated, the silicates and the potash; but in all dells and pond-holes in the woods and pastures and swamps grows a rich and various crop only unreaped by man.

 Magma jerak.org   (Site not responding. Last check: 2007-10-30)
Magma is a complex high-temperature (between 650 and 1200 °C) silicate solution that is ancestral to all igneous rock s.
The presence of volatile phases in a rock acts similar to a solvent, assisting in the break-down of the strong silicate bonds in the minerals of a rock.
This is a very important process for generating melts, as the presence of even 1% water may reduce the temperature of melting by as much as 100°C. Conversely, the loss of water and volatiles from a magma may cause it to essentially freeze or soldify.

Zinc beryllium silicate and beryllium oxide were used widely in fluorescent tube phosphors, until this application was abandoned in 1949 because of considerable health hazards (Newland, 1982).
The main use of beryllium arises from the outstanding properties that it confers on other metals; about 72% of the beryllium produced is used in the form of beryllium-copper and other alloys.
