CAS 7440-33-7: Tungsteno

Descripción:
Tungsteno, con el número CAS 7440-33-7, es un metal de transición conocido por sus notables propiedades. Tiene el punto de fusión más alto de todos los elementos, lo que lo hace excepcionalmente valioso en aplicaciones de alta temperatura. Tungsteno se caracteriza por su naturaleza densa, dura y quebradiza, con un brillo metálico. Exhibe una excelente conductividad tanto para el calor como para la electricidad, lo que lo hace adecuado para diversas aplicaciones eléctricas. Químicamente, Tungsteno es relativamente inerte, resistiendo la corrosión y la oxidación a temperatura ambiente, aunque puede reaccionar con halógenos y ácidos a temperaturas elevadas. Sus compuestos, como el carburo de Tungsteno, se utilizan ampliamente en herramientas de corte y abrasivos debido a su dureza. Tungsteno también se utiliza en la producción de filamentos para bombillas y en las industrias aeroespacial y militar por su resistencia y durabilidad. Además, Tungsteno tiene un papel significativo en la producción de aleaciones, mejorando las propiedades de los materiales utilizados en entornos exigentes. En general, la combinación única de propiedades físicas y químicas de Tungsteno lo convierte en un material esencial en diversas aplicaciones industriales.

    Producto controlado
    CAS:
    Tungsten metal powder is a reactive chemical element that has an atomic number of 74 and an atomic weight of 183.85. It is used in the production of light bulbs, vacuum tubes, and filaments for electric lamps. Tungsten metal powder reacts with water vapor to produce hydrogen gas and tungsten oxide, which can be detected by kinetic energy analysis. Tungsten metal powder is also used as a catalyst in the laboratory during reactions involving molybdenum or dimethyl fumarate. The reaction mechanism has been elucidated through x-ray crystal structures and electrochemical impedance spectroscopy (EIS). Tungsten metal powder has a high chemical stability, making it useful for analytical methods such as laser ablation mass spectrometry (LA-MS) and EIS analysis.
