CAS 7440-02-0: Nichel
Descrizione:
Nichel è un metallo di transizione con il simbolo chimico Ni e il numero CAS 7440-02-0. È caratterizzato dal suo aspetto bianco argenteo ed è noto per la sua alta duttilità e malleabilità. Nichel ha un punto di fusione e un punto di ebollizione relativamente elevati rispetto a molti altri metalli, rendendolo adatto per applicazioni ad alta temperatura. Mostra un'eccellente resistenza alla corrosione, in particolare in ambienti alcalini, motivo per cui è spesso utilizzato in leghe e rivestimenti per migliorare la durabilità. Nichel è ferromagnetico a temperatura ambiente, il che significa che può essere magnetizzato. In termini di reattività chimica, Nichel può formare vari stati di ossidazione, con +2 che è il più comune nei composti. Reagisce prontamente con gli acidi, liberando gas idrogeno, e può anche formare ioni complessi in soluzione. Nichel è un elemento traccia essenziale nei sistemi biologici, svolgendo un ruolo in determinati processi enzimatici, ma l'esposizione eccessiva può essere tossica. Le sue applicazioni spaziano dalla produzione di acciaio inossidabile a batterie e catalizzatori in reazioni chimiche.

CAS:Prodotto controllatoNickel 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.Formula:NiColore e forma:Suspension PowderPeso molecolare:58.69 g/molNickel powder, -150+200 mesh, 99.8% (metals basis)
