CAS 7440-03-1: Niobio
Descripción:
Niobio, con el símbolo químico Nb y el número CAS 7440-03-1, es un metal de transición conocido por su alto punto de fusión y excelente resistencia a la corrosión. Es un metal de color gris plateado que es dúctil y se puede moldear fácilmente. Niobio se utiliza principalmente en la producción de aleaciones de acero de alta resistencia, que mejoran la resistencia y tenacidad de los materiales utilizados en la construcción y la fabricación. Tiene una estructura cristalina cúbica centrada en el cuerpo y exhibe propiedades superconductoras a bajas temperaturas, lo que lo hace valioso en aplicaciones como máquinas de resonancia magnética y aceleradores de partículas. Niobio también es resistente a la oxidación y puede formar una capa de óxido protectora, lo que contribuye a su durabilidad en diversos entornos. Además, es relativamente raro en la corteza terrestre y se obtiene principalmente de minerales como columbita y pirocloro. Debido a sus propiedades únicas, Niobio desempeña un papel significativo en la tecnología moderna y la ciencia de materiales.
