CAS 7440-02-0: Níquel
Descrição:
Níquel é um metal de transição com o símbolo químico Ni e o número CAS 7440-02-0. É caracterizado por sua aparência prateada e é conhecido por sua alta ductilidade e maleabilidade. Níquel tem um ponto de fusão e um ponto de ebulição relativamente altos em comparação com muitos outros metais, tornando-o adequado para aplicações em altas temperaturas. Apresenta excelente resistência à corrosão, particularmente em ambientes alcalinos, razão pela qual é frequentemente utilizado em ligas e revestimentos para aumentar a durabilidade. Níquel é ferromagnético à temperatura ambiente, o que significa que pode ser magnetizado. Em termos de reatividade química, Níquel pode formar vários estados de oxidação, sendo +2 o mais comum em compostos. Reage prontamente com ácidos, liberando gás hidrogênio, e também pode formar íons complexos em solução. Níquel é um elemento traço essencial em sistemas biológicos, desempenhando um papel em certos processos enzimáticos, mas a exposição excessiva pode ser tóxica. Suas aplicações variam desde a produção de aço inoxidável até baterias e catalisadores em reações químicas.

CAS:Produto ControladoNickel is a transition metal with atomic number 28. It is found in many minerals, such as, nickel sulfide, nickel oxide, niccolite, nickeline and pentlandite, among others; it is used in coins and as a component of stainless steel in metallurgy. Nickel is an important reagent in organic chemistry, being used as catalyst for hydrogenation reactions, also in the form of Ni nanoparticles. Additionally, in the form of organic halides such as NiCl2 or NiBr2, it is useful for cyclization reactions with Grignard reagents. Nickel also has antioxidative properties and can be used to remove harmful substances from water. The flow rate of nickel depends on its crystal structure; it has high bulk density and low light absorption.Fórmula:NiCor e Forma:Suspension PowderPeso molecular:58.69 g/molNickel powder, -150+200 mesh, 99.8% (metals basis)
