CAS 7440-58-6

Háfnio

Descrição:

Háfnio é um metal de transição com o símbolo químico Hf e o número CAS 7440-58-6. É caracterizado por seu alto ponto de fusão, que é um dos mais altos entre todos os elementos, tornando-o útil em aplicações de alta temperatura. Háfnio tem uma aparência cinza-prateada e exibe um brilho metálico. É conhecido por sua excelente resistência à corrosão, particularmente em ambientes ácidos, devido à formação de uma camada de óxido protetora. Háfnio tem uma densidade relativamente alta e é frequentemente usado em reatores nucleares, pois tem uma forte capacidade de absorver nêutrons. Além disso, é utilizado na produção de ligas de alto desempenho e na indústria de semicondutores por suas propriedades como material dielétrico. Háfnio é tipicamente encontrado em minerais de zircônio e é extraído através de processos como cristalização fracionada. Seu comportamento químico é semelhante ao do zircônio, e forma vários compostos, incluindo óxido de Háfnio, que é significativo em eletrônica e óptica. No geral, as propriedades únicas de Háfnio o tornam valioso em várias aplicações tecnológicas avançadas.
