Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive.

Silicon (Si) is a light chemical element that combines with oxygen and other elements to form silicates. Silicon in the form of silicates constitutes more than 25% of the Earth's crust. Silica (SiO 2) as quartz or quartzite is used to produce silicon ferroalloys and silicon metal.

Element association of Silicon in the Mineral World This table compares the known valid mineral species listed listed with Silicon and the other elements listed based on the official IMA formula.

2025年1月18日 · Silicon, a nonmetallic chemical element in the carbon family that makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen. Learn more about the characteristics, distribution, and uses of silicon in this article.

Silicon mineral data, information about Silicon, its properties and worldwide locations.

There are hundreds of silicon-bearing minerals, including quartz, probably the second most common mineral on Earth. Silicon is chiefly obtained from quartz, which is not much more difficult to mine than scooping up sand. Silicon is also obtained from the minerals mica and talc.

Mineral quartz is 99 percent silicon, one of the most important raw materials of the 21st century. Silicon is in every computer, mobile phone and, of course, in solar cells.

The gray shading in the BSE mage consists mainly of pure silicon (Si metal). The brighter areas are composed of Fe-silicide. (AmMin, 88:1818). Location: Found in a cobble at a beach along the Turkish coast of the Mediterranean Sea, around 150 km NW from Izmir, and is most likely derived from Tertiary volcanic rocks outcropping in the area.

Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is …

silica mineral, any of the forms of silicon dioxide (SiO 2), including quartz, tridymite, cristobalite, coesite, stishovite, lechatelierite, and chalcedony. Various kinds of silica minerals have been produced synthetically; one is keatite.
