USES :
Tungsten(VI) oxide,
also known as tungsten trioxide
or tungstic anhydride, WO3,
is a chemical compound containing oxygen and the transition metal tungsten.
It is obtained as an intermediate in the recovery of tungsten from its
minerals. Tungsten ores are treated with alkalis to
produce WO3. Further reaction with carbon or hydrogen gas reduces tungsten trioxide to the pure metal.
