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. WO3 + 3H2 → W + 3H2O 2WO3 + 3C → 2W + 3CO2 Tungsten trioxide 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. Preparation Tungsten trioxide can be prepared in several different ways. CaWO4, or scheelite, is allowed to react with HCl to produce tungstic acid, which decomposes to WO3 and water at high temperatures. Related Products: Ammonium Paratungstate Ammonium paratungstate (APT) is an important intermediate compounds of tungsten hydrometallurgical process, appearance is white crystalline powder, insoluble in water, soluble in alcohol and ether. Ammonium Metatungstate Ammonium metatungstate(AMT) is an important intermediate compounds of tungsten hydrometallurgical process, appearance is white crystalline powder, solubility in water is the largest in the tungsten compounds which over 300g WO3/100ml H2O (in 25℃). Sodium Tungstate Sodium tungstate, a tungstate of sodium, is useful as a source of tungsten. It is prepared from tungsten ores used to manufacture tungsten by reducing it. Tungstic Acid Tungstic acid refers to hydrated forms of tungsten trioxide, WO3. The simplest form, the monohydrate, is WO3H2O, the dihydrate WO3·2H2O is also known. The solid state structure of WO3· H2O consists of layers of octahedrally coordinated WO5(H2O) units where 4 vertices are shared. Blue Tungsten Oxide Blue tungsten oxide refers to a class of dark blue compound containing tungsten (Ⅵ) and tungsten (V) mixed valence state. Blue tungsten oxide is the product of reductant and tungsten compounds. Composition of blue tungsten oxide is complex, among which there are also intermediate oxides like WO2 and W4.
