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.

CAS:Producto 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:NiForma y color:Suspension PowderPeso molecular:58.69 g/molNickel powder, -150+200 mesh, 99.8% (metals basis)
