Tungsten Element information, properties and uses

Tungsten carbide is immensely hard and is very important to the metal-working, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating to 2200°C. It makes excellent cutting and drilling tools, including a new ‘painless’ dental drill which spins at ultra-high speeds.

Tungsten Periodic table

Source: Tungsten is not found free in nature. The principal ores of tungsten are wolframite (an iron manganese tungstate) and scheelite (calcium tungstate, CaWO 3). Commercially, the metal is obtained by reducing tungsten oxide with hydrogen or carbon. Isotopes: Tungsten
