CAS 7440-21-3

Silício

Descrição:

Silício, com o número CAS 7440-21-3, é um elemento metaloide que desempenha um papel crucial em várias indústrias, particularmente em eletrônica e ciência dos materiais. É caracterizado pelo seu brilho metálico e natureza quebradiça em sua forma cristalina. Silício tem um alto ponto de fusão e é um mau condutor de eletricidade à temperatura ambiente, mas sua condutividade aumenta significativamente quando dopado com impurezas, tornando-se um material semicondutor fundamental. É abundante na crosta terrestre, encontrado principalmente na forma de silicatos e dióxido de Silício. Silício é essencial na produção de vidro, cerâmica e concreto, e é um componente chave na fabricação de células solares e chips de computador. Além disso, Silício exibe uma capacidade de ligação tetravalente, permitindo-lhe formar ligações covalentes estáveis com outros elementos, o que é vital para criar vários compostos à base de Silício. Sua versatilidade e propriedades únicas fazem de Silício uma pedra angular da tecnologia moderna e da engenharia de materiais.
