Silicon sputtering targets(Si)Product overview

Silicon is a hard and fragile crystal with a grayish blue metallic luster in its appearance, and is also a tetravalent metal like semiconductor. Silicon is one of the 14th group elements in the periodic table: carbon is above it, followed by germanium, tin, lead, and lanthanum. Due to its high affinity for oxygen, it was not until 1823 that it was first successfully purified by Yongs Betzelius. Its melting point and boiling point are 1414 degrees Celsius and 3265 degrees Celsius, respectively, and it ranks second among metals and non-metals, second only to boron. Silicon ranks eighth among the most common elements in the universe, but its elemental distribution in the earth's crust is very rare. It is often widely distributed in various forms such as silica or silicate in soil, sand, and asteroids and planets. The composition of the earth's crust is more than 90% silicate, making silicon the second most abundant element in the earth's crust, second only to oxygen.

The element silicon also has a significant impact on the world economy. Silicon is usually processed together with natural minerals and has a wide range of uses, including clay, silica sand, and stone used in the construction industry. The mortar and plaster composition of Portland cement also contains silicate, which can be mixed with silica sand and gravel to form concrete for use in walkways, foundations, and roads. They are also used in white ceramics, such as porcelain, as well as in the manufacture of traditional quartz soda lime glass and many other special glasses. The most widely known use of silicon is to synthesize synthetic polymers based on polysiloxane polymers. Some silicon compounds, such as silicon carbide, can be used as abrasives or high-strength ceramic components. Most ionized silicon is used in steel making, aluminum casting, and high-quality chemical industries (typically in the manufacture of fumed silica). More significantly, the semiconductor electronics industry uses a small proportion of high purity silicon (less than 10%), which is a necessary element in integrated circuits, and most computers, mobile phones, and modern technology rely on it.

Silicon is a semiconductor material that can be used to make semiconductor devices, solar panels, optical fibers, and integrated circuits. It can also be used in the form of alloys (such as ferrosilicon) for automotive and mechanical parts. It is also used in cermets together with ceramic materials. It can also be used to manufacture glass, concrete, bricks, refractory materials, siloxanes, and silanes. Combined with iron, it can become silicon steel, which is a wear-resistant steel component commonly used in various tools. In addition, silicon is also one of the main components of stainless steel, used to make stainless steel have wear-resistant properties.
