EC Number 215-231-4. MDL number MFCD00011466. eCl@ss 38180904 . PubChem Substance ID 24852293. NACRES NA.23 For tungsten the ores are concentrated by magnetic and mechanical processes, and the concentrate is then fused with alkali. The crude melts are leached with water to give solutions of sodium tungstate, from which hydrous tungsten trioxide is precipitated upon acidification, and the oxide is then dried and reduced to metal with hydrogen.

Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO 3, 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 WO 3. Tungsten oxide is the oxide state of tungsten and an important intermediate to produce tungsten from concentrate, the four main products are tungsten dioxide, tungsten trioxide, blue tungsten oxide and violet tungsten oxide. Tungsten(VI) oxide powder, 99.995% trace metals basis Synonym: Tungstic anhydride CAS Number 1314-35-8.
