tungsten oxide (VI), also known as tungsten trioxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and metal tungsten transition. It is obtained as an intermediate in the recovery of tungsten from its minerals. [1] Tungsten minerals are treated with alkali to produce WO3. Further reaction with carbon or gaseous hydrogen reduces tungsten trioxide to pure metal. [Quote required]

2 WO3 + 3 C → 2 W + 3 CO2 (high temperature)

WO3 + 3 H2 → W + 3 H2O (550 – 850 ° C)

tungsten oxide (VI) occurs naturally as hydrates, including minerals: H2O tungstite WO3, WO3 meymacite 2H2O, and hydrotungstite (of the same composition of meymacite, although sometimes written as H2WO4). These minerals are rare to very rare secondary tungsten minerals.
