Nanostructured tungsten carbide synthesis by carbothermic ...

Before and around 1920, tungsten was only important as a steel alloying element and as a filament in incandescent lamps. However, since 1930, cemented carbides (also called hardmetals) attained a greater share in tungsten consumption. The main component of hardmetals is tungsten carbide (WC), one of the hardest materials.
