Tungsten Oxide, WO3-x Applied for Transparent Thermal Insulation Material

Tungsten oxide, WO3-x, may be used to prepare transparent thermal insulation material for applying in architectural glass such as sun room, greenhouse, and glass windows of vehicles such as airplanes, to make these glasses have the characteristics of heat insulation, heat preservation and energy conservation, and environmental protection. With the promotion of its application, tungsten oxide nanopowder is becoming more and more known to people.

But do you know what the XRD spectrum of tungsten oxide powder looks like after reduction? The above figure shows the XRD patterns of the reduced tungsten oxide powder. Wherein, WO2.92 and WO2.83 are in accordance with JCPDS30–1387 and JCPDS36–0103, respectively, with monoclinic phase. Since the conditions of reduction have random selectivity for x in WO3–x, the value of x can only be determined by XRD. The data can be imported into the XRD analysis software, and the phases of WO2.92 and WO2.83 are determined by the phase fitting to determine the value of x.
