CAS 7440-21-3
:Silicon
Description:
Silicon, with the CAS number 7440-21-3, is a metalloid element that plays a crucial role in various industries, particularly in electronics and materials science. It is characterized by its shiny, metallic luster and brittle nature in its crystalline form. Silicon has a high melting point and is a poor conductor of electricity at room temperature, but its conductivity increases significantly when doped with impurities, making it a fundamental semiconductor material. It is abundant in the Earth's crust, primarily found in the form of silicates and silicon dioxide. Silicon is essential in the production of glass, ceramics, and concrete, and it is a key component in the manufacture of solar cells and computer chips. Additionally, silicon exhibits a tetravalent bonding capability, allowing it to form stable covalent bonds with other elements, which is vital for creating various silicon-based compounds. Its versatility and unique properties make silicon a cornerstone of modern technology and materials engineering.
