Cs0.32WO3 Applied for Infrared Ultraviolet Shielding Material

Cs0.32WO3 for preparing infrared ultraviolet shielding material may be highly crystalline and hexagonal single-phase Cs0.32WO3 nanoparticles that exhibit absorption in the near-infrared region. According to the experts, the Cs0.32WO3 nano particles can be successfully synthesized by a flame-assisted spray pyrolysis followed by annealing under a reducing gas atmosphere. Well, what are the advantages of using a flame-assisted spray pyrolysis to prepare Cs0.32WO3 nano powder?

Unlike conventional methods, the proposed process (flame-assisted spray pyrolysis, short for FASP) is promising for rapid and energy effective production of Cs0.32WO3 nanoparticles without the need for a grinding process. Specifically, the FASP process has several advantages, including a short reaction time and the ability to yield products with high purity and good energy efficiency. In particular, the use of a grinding process was avoided. Although grinding processes have been widely used in industrial processes, it remains difficult to control the particle size precisely. Furthermore, the surface of the nanoparticles can be damaged, and there is a possibility of contamination during the grinding process. Conversely, the FASP process can be used to prepare highly crystalline nanoparticles without contamination. It is easy to scale up and has the potential to rapidly prepare nanoparticles within several minutes.
