Exposure to various tungsten oxides and suboxides occurs in the metallurgical processes used to produce tungsten powder. Tungsten Oxide, or tungsten trioxide, is a yellow transition metal oxide with the formula: WO 3.Tungsten oxide is generally produced through the treatment of tungsten ore with alkalis, while additional treatment with high temperature carbon or hydrogen gas will reduce the oxide to pure metal tungsten.

Tungsten (IV) oxide is the chemical compound with the formula WO 2. The bronze-colored solid crystallizes in a monoclinic cell. The rutile -like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). Each tungsten center has the d 2 configuration, which gives the material a high electrical conductivity.
