Tungsten can be extracted from its oxide with carbon but that can leave impurities which make the metal more brittle. If pure tungsten is needed, the ore is reduced using hydrogen instead. This happens in a furnace at temperatures above 700 degrees C. Tungsten is the only metal reduced on a large scale using hydrogen.
Tungsten carbide finds use in drill bits as a result of its hardness. To extract tungsten from its ore without forming the carbide, hydrogen is reacted with tungsten oxide at a high temperature, displacing the metal. For the metals highest in the reactivity series, extraction using carbon simply isn''t a possibility.
