Tungsten oxide, also known as tungsten trioxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and the transition metal tungsten
Obtained as an intermediate in the recovery of tungsten from its minerals
[1] Tungsten ores are treated with alkalis to produce WO3
Further reaction with carbon or hydrogen gas reduces tungsten trioxide to the pure metal
2 WO3 + 3 C → 2 W + 3 CO2 (high temperature)
WO3 + 3 H2 → W + 3 H2O (550-850 °C)
Tungsten(VI) oxide occurs naturally in form of hydrates, which include minerals: tungstite WO3·H2O, meymacite WO3·2H2O and hydrotungstite (of same composition as meymacite, however sometimes written as H2WO4)
These minerals are rare to very rare secondary tungsten minerals
