As a heat insulation film, WO3 film is more and more popular in building energy efficiency. Also, such a smart film may be applied to automobiles. Well, do you know any other advantages of WO3 heat insulation film? Good temperature resistance, excellent electrical properties, tough tear resistance, good flexibility, excellent weatherability, outstanding stress crack resistance, exceptional chemical resistance, good inertness and dielectric insulation properties. So, what is WO3?
WO3 is also known as tungsten trioxide, which becomes a conductor by reduction of oxygen and/or doping with other elements. Magneli phase such as WO2.72 is a typical reduced conductive phase of tungsten trioxide. Cesium doped tungsten oxide, CsxWO3, is a typical alkali-doped conductive phase, and belongs to a family of so-called tungsten bronze.
