WO3 Tungsten Trioxide powder CAS 1314-35-8 used as a pigment in
ceramics and paints
Brief Description of Tungsten Trioxide powder WO3
Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and the transition metal
tugsten
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.
