Tungsten Trioxide (WO3) Powder – Superfine Description
Tungsten trioxide, also called tungsten (VI) oxide or tungstic anhydride, is a thermally stable and water-insoluble tungsten compound. Tungsten Trioxide is generally immediately available in most volumes. Ultra-high purity, high purity, submicron and nanopowder forms may be considered.
Tungsten Trioxide (WO3) – Superfine Application
-Tungsten trioxide is widely used to manufacture tungstates for x-ray screen phosphors, fireproofing fabrics, and gas sensors.
-Tungsten (VI) oxide has specialized use in the production of electrochromic windows.
-WO3 is also used as a pigment in ceramics and paints due to its yellow color.
