Application

Blue Tungsten Oxide is a highly insoluble thermally stable Tungsten source suitable for glass, optic and ceramic applications. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal High Purity (99.999%) Blue Tungsten Oxide (WO2) Powderoxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Blue Tungsten Oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder. Blue Tungsten Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. 


Packing
