CsxWO3 Applied for Near Infrared Shielding Material

CsxWO3 may be applied for producing near infrared shielding material. The obtained material can be used in the field of construction or automobile. With the application of this new type of heat insulation material, more and more people are beginning to pay attention to this environmentally friendly material. For example, scholars and researchers may be concerned about the crystal structure of the cesium tungsten bronze powder, i.e. the result of XRD analysis.

In this regard, the expert used XRD instrument to analyze the crystal structure of the sample: Cu Ka (λ = 0.154nm), tube voltage 40 kV, tube current 40mA, step scan mode, step length 0.0167°, each step stays 0.1s, 2θ scan range 10°-80°. And it can be seen from the experimental results that when the Cs/W ratio is 0.1 and 0.2, there are two mixed phases of hexagonal Cs0.32WO3 and WO3, which are due to the low concentration of Cs in the reaction system. As the materials are not doped completely, the free carrier concentration in the cesium tungsten bronze structure is low. When the Cs/W ratio is 0.3-0.6, the diffraction peak of the sample is completely corresponding to Cs0.32WO3, and there is no extra peak, which proves to be Cs0.32WO3 structure.
