CAS 7440-21-3

Silizium

Beschreibung:

Silizium, mit der CAS-Nummer 7440-21-3, ist ein metalloides Element, das eine entscheidende Rolle in verschiedenen Industrien spielt, insbesondere in der Elektronik und Materialwissenschaft. Es zeichnet sich durch seinen glänzenden, metallischen Glanz und seine spröde Natur in kristalliner Form aus. Silizium hat einen hohen Schmelzpunkt und ist bei Raumtemperatur ein schlechter elektrischer Leiter, aber seine Leitfähigkeit steigt erheblich, wenn es mit Verunreinigungen dotiert wird, was es zu einem grundlegenden Halbleitermaterial macht. Es ist in der Erdkruste reichlich vorhanden, hauptsächlich in Form von Silikaten und Silizium-Dioxid. Silizium ist entscheidend für die Herstellung von Glas, Keramiken und Beton und ist ein Schlüsselbestandteil in der Herstellung von Solarzellen und Computerchips. Darüber hinaus zeigt Silizium eine tetravalente Bindungsfähigkeit, die es ihm ermöglicht, stabile kovalente Bindungen mit anderen Elementen zu bilden, was für die Schaffung verschiedener Silizium-haltiger Verbindungen von entscheidender Bedeutung ist. Seine Vielseitigkeit und einzigartigen Eigenschaften machen Silizium zu einem Grundpfeiler der modernen Technologie und Materialtechnik.
