Tungsten oxide - Wikipedia
Tungsten has several oxidation states, and therefore oxides: Tungsten(III) oxide; Tungsten(IV) oxide, also known as tungsten dioxide; Tungsten(VI) oxide, also known as tungsten trioxide; Tungsten pentoxide
Tungsten Oxide - an overview | ScienceDirect Topics
Tungsten oxide is a versatile semiconductor material with multiple oxidation states, which makes it suitable for various applications such as photochromic, electrochromic, photocatalytic, and gas-sensor applications.
Tungsten(IV) oxide - Wikipedia
Tungsten(IV) oxide is the chemical compound with the formula W O 2. The bronze-colored solid crystallizes in a monoclinic cell. [1] The rutile-like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). [1] Each tungsten center has the d 2 configuration, which gives the material a high electrical ...
Tungsten trioxide - Wikipedia
Tungsten(VI) oxide, also known as tungsten trioxide is a chemical compound of oxygen and the transition metal tungsten, with formula WO 3. The compound is also called tungstic anhydride, reflecting its relation to tungstic acid H 2 WO 4. It is a light yellow crystalline solid. [1]
