CAS 7440-47-3: Cromo
Descripción:
Cromo, con el número CAS 7440-47-3, es un metal de transición conocido por su alta resistencia a la corrosión y dureza. Tiene un número atómico de 24 y está representado por el símbolo Cr en la tabla periódica. Cromo exhibe un brillo metálico gris plateado y se encuentra principalmente en la naturaleza en forma de mineral de cromita. Se caracteriza por su capacidad para formar varios estados de oxidación, siendo +3 y +6 los más comunes en compuestos. Cromo se utiliza ampliamente en la producción de acero inoxidable y otras aleaciones, mejorando su resistencia y resistencia a la oxidación. Además, juega un papel crucial en la fabricación de pigmentos, como el óxido de Cromo, que aporta colores vibrantes a cerámicas y pinturas. En términos de reactividad química, Cromo puede reaccionar con oxígeno y otros no metales, formando óxidos y otros compuestos. Si bien es esencial en cantidades traza para funciones biológicas, ciertos compuestos de Cromo, particularmente el Cromo hexavalente, son conocidos por ser tóxicos y cancerígenos, lo que requiere un manejo y regulación cuidadosos.
