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.
