Silicon is the eighth most common element in the universe by mass, but very rarely occurs in its pure form in the Earth's crust. It is widely distributed throughout space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide (silica) or silicates. 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 is the only journal devoted to the spectacular diversity of silicon covering materials chemistry, physics, biology, and engineering, plus environmental science The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. For this, hyperpure silicon is needed. The silicon is selectively doped with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties.

Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust. Today, silicon is produced by heating sand (SiO 2) with carbon to temperatures approaching 2200°C. Silicon is the second most abundant element on earth after oxygen, representing nearly 26% of the earth's crust by mass. It is not present as a single element but is always associated with another element, most often oxygen, mainly in the form of silicates (SiO2). Silicon is a brittle and hard crystalline solid. It has blue-grey metallic lustre. Silicon, in comparison with neighbouring elements in the periodic table, is unreactive. The symbol for silicon is Si with atomic number 14. It has a very high melting and boiling point.
