CAS 7440-47-3

Cromo

Descrição:

Cromo, com o número CAS 7440-47-3, é um metal de transição conhecido por sua alta resistência à corrosão e dureza. Tem um número atômico de 24 e é representado pelo símbolo Cr na tabela periódica. Cromo exibe um brilho metálico cinza prateado e é encontrado principalmente na natureza na forma de minério de cromita. É caracterizado por sua capacidade de formar vários estados de oxidação, sendo +3 e +6 os mais comuns em compostos. Cromo é amplamente utilizado na produção de aço inoxidável e outras ligas, aumentando sua resistência e resistência à oxidação. Além disso, desempenha um papel crucial na fabricação de pigmentos, como o óxido de Cromo, que confere cores vibrantes a cerâmicas e tintas. Em termos de reatividade química, Cromo pode reagir com oxigênio e outros não metais, formando óxidos e outros compostos. Embora seja essencial em quantidades traço para funções biológicas, certos compostos de Cromo, particularmente o Cromo hexavalente, são conhecidos por serem tóxicos e cancerígenos, exigindo manuseio e regulamentação cuidadosos.
