Tungsten trioxide powder, as a near-infrared shielding material, may be prepared by organic induction synthesis method.
Regarding the synthesis of tungsten trioxide by this method, it is reported that tungsten trioxide with sharp-edged nanoscale bulk crystal may be synthesized from 4,4/-bipiyridine and multiple metal oxides. While the related research has not been deepened. However, the microstructure and morphology of WO3 have a significant effect on its photochromic properties. Therefore, organic methods are used to provide a new way for the synthesis of tungsten trioxide with novel structures and excellent photochromic properties.
Organic induction provides a new method for the synthesis of inorganic materials with special structure and morphology. The induction product is a new type of material with unique appearance and specific dings. And therefore, these materials have special physical and chemical properties. It means that they have potential application prospects in many different fields. For example, WO3 prepared by this method may be applied in the field of thermal insulation.
