Nano particle size cesium tungsten oxide, also known as nano cesium tungsten bronze, may be used to prepare thermal insulation dispersion liquid and be used to produce thermal insulation film for applying in architectural glass.
And therefore the obtained glass has excellent thermal insulation property. Also, such glass will be resistant to ultraviolet radiation. At the time, the glass of cesium tungsten bronze nanoparticles may avoid the fading and aging of indoor accessories and reduce the occurrence of human skin diseases to a certain extent. In this regard, experts said that the raw material cesium tungsten bronze nano particles can be prepared using Na2WO4?2H2O and Cs2CO3 as raw materials or WCl6 and CsOH?2H2O as raw materials.

Cs0.33WO3 particles prepared from optical properties analysis: the Cs0.33WO3 particles prepared using Na2WO4?2H2O and Cs2CO3 as raw materials have no obvious performance in visible light transmittance and near-infrared light shielding rate. However, after nitrogen treatment for 2 hours, their performance is greatly improved. The visible light transmittance is up to 56% and the near-infrared light transmittance is 24.5%. The Cs0.33WO3 particles prepared using WCl6 and CsOH?2H2O as raw materials has good performance in visible light transmittance and near-infrared light shielding. The optical properties of the unheated powder are slightly better than those of Na2WO4?2H2O and Cs2CO3. The visible light transmittance of the Cs0.33WO3 particles increased after heat treatment, but the overall performance of coating does not increase significantly.
