Scheele discovered "Tungsten" in 1781; however, it took 150 years more before the efforts of Scheele and his successors led to the use of tungsten carbide in the industry. We use cookies to enhance your experience.
Tungsten carbides are possible low-cost replacements for noble metal catalysts, but the role of different carbide stoichiometries (W 2 C, WC) and their polymorphs for catalytic behavior is poorly understood. We develop a "dynamic, isothermal" carburization of WO 3 in a mixture of CH 4 and H 2 to control phase composition and catalytic …

When it's ready, the die set is filled with carbide powder, which is pressed or compacted to form a "green body.". The green part is then sintered to create a fully dense carbide part. Sometimes sintered parts require finishing operations, usually grinding, polishing or EDM due to the material's hardness. Using this process, it can be ...

Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the powdered …
