CAS 7440-02-0
:Níquel
Descripción:
Níquel es un metal de transición con el símbolo químico Ni y el número CAS 7440-02-0. Se caracteriza por su apariencia blanco plateada y es conocido por su alta ductilidad y maleabilidad. Níquel tiene un punto de fusión y un punto de ebullición relativamente altos en comparación con muchos otros metales, lo que lo hace adecuado para aplicaciones a altas temperaturas. Exhibe una excelente resistencia a la corrosión, particularmente en entornos alcalinos, razón por la cual a menudo se utiliza en aleaciones y recubrimientos para mejorar la durabilidad. Níquel es ferromagnético a temperatura ambiente, lo que significa que puede ser magnetizado. En términos de reactividad química, Níquel puede formar varios estados de oxidación, siendo +2 el más común en compuestos. Reacciona fácilmente con ácidos, liberando gas hidrógeno, y también puede formar iones complejos en solución. Níquel es un elemento traza esencial en sistemas biológicos, desempeñando un papel en ciertos procesos enzimáticos, pero la exposición excesiva puede ser tóxica. Sus aplicaciones van desde la producción de acero inoxidable hasta baterías y catalizadores en reacciones químicas.
