CAS 7440-19-9: Samario
Descripción:
Samario es un elemento metálico de color blanco plateado clasificado como un lantánido en la tabla periódica, con el número atómico 62. Es relativamente estable en el aire y no se empaña fácilmente, aunque puede reaccionar con agua y ácidos para formar hidróxido de Samario y sales de Samario. Samario exhibe un alto punto de fusión y es conocido por sus propiedades magnéticas, lo que lo hace útil en la producción de imanes permanentes, particularmente imanes de Samario-cobalto, que son conocidos por su alta resistencia a la desmagnetización. Además, Samario se utiliza en diversas aplicaciones, incluidos reactores nucleares, donde actúa como un absorbente de neutrones, y en la fabricación de fósforos para tubos de televisión en color y luces LED. El elemento se obtiene típicamente de minerales como monacita y bastnasita, y a menudo se utiliza en forma de aleaciones o compuestos. Los isótopos de Samario tienen aplicaciones en medicina, particularmente en el tratamiento del cáncer, debido a sus propiedades radiactivas. En general, Samario es un elemento versátil con una importancia industrial y tecnológica significativa.
