Wolfram trioxide (WO3)-Pulver - Superfine Description
Wolfram trioxide, also known as Tungsten(VI) oxide or tungsten acid anhydride, is a thermally stable and water‐insoluble tungsten compound. This compound is available in most quantities without delay. Ultra‐high purity, high purity, submicron and nanopowder forms are offered.

Wolfram trioxide (WO3) - Superfine Application
Wolfram trioxide is frequently used in the production of tungstenates for X-ray screen phosphors, refractory materials and gas sensors. Tungsten(VI) oxide is specifically employed in the manufacture of electrochromic windows. WO3 is utilised as a pigment in ceramics and paints because of its yellow colour.
