Beschreibung

Allgemeine Beschreibung

Tungsten(VI) oxide, also known as tungsten trioxide, is a chemical compound with the formula WO3. Our material is a yellow crystalline solid. It is a versatile material with applications in electrochromic devices, sensors, photocatalysis, energy storage, and various other fields in material science. WO3 is used in gas and humidity sensors due to its sensitivity to various gases. It is also used as a starting material for the synthesis of tungstates, which have applications in x-ray screen phosphors and mineral separation.

Anwendung
