CAS 7440-47-3
:Cromo
Descrizione:
Cromo, con il numero CAS 7440-47-3, è un metallo di transizione noto per la sua alta resistenza alla corrosione e durezza. Ha un numero atomico di 24 ed è rappresentato dal simbolo Cr nella tavola periodica. Cromo presenta una lucentezza metallica grigio argento ed è principalmente trovato in natura sotto forma di minerale di cromite. È caratterizzato dalla sua capacità di formare vari stati di ossidazione, con +3 e +6 che sono i più comuni nei composti. Cromo è ampiamente utilizzato nella produzione di acciaio inossidabile e altre leghe, migliorando la loro resistenza e resistenza all'ossidazione. Inoltre, gioca un ruolo cruciale nella produzione di pigmenti, come l'ossido di Cromo, che conferisce colori vivaci a ceramiche e vernici. In termini di reattività chimica, Cromo può reagire con l'ossigeno e altri non metalli, formando ossidi e altri composti. Sebbene sia essenziale in quantità traccia per le funzioni biologiche, alcuni composti di Cromo, in particolare il Cromo esavalente, sono noti per essere tossici e cancerogeni, richiedendo un'attenta manipolazione e regolamentazione.
