CAS:Producto controladoTungsten 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.Pureza:Min. 95%Tungsten gauze, gold plated
