Tungsten, (or Wolfram as it is known in many parts of the world) is an extremely hard and very dense gray to white metallic element extracted from wolframite, scheelite and other minerals. Tungsten has the highest melting point, lowest coefficient of expansion and lowest vapor pressure of any metal. It is also corrosion resistant and does not break down or decompose.

Tungsten trioxide

Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO 3, is a chemical compound containing oxygen and the transition metal tungsten is obtained as an intermediate in the recovery of tungsten from its minerals. Tungsten ores are treated with alkalis to produce WO 3.Further reaction with carbon or hydrogen gas reduces tungsten trioxide to the pure metal.
