Cs0.32WO3 for preparing ceramic microsphere is cesium doped tungsten oxide nano powder that has been regarded as highly promising NIR shielding material. Until now, cesium doped tungsten oxide nanoparticles have been synthesized via solid state, hydrothermal, water controlled-release solvothermal, and thermal plasma synthesis methods that need high energy, costs, or long time. Thus, it is necessary to synthesize cesium doped tungsten oxide nanoparticles using a rapid and energy effective method to make it feasible for large-scale and practical applications.

For example, the experts using a flame-assisted spray pyrolysis to synthesize highly crystalline and hexagonal single-phase Cs0.32WO3 nanoparticles followed by annealing under a reducing gas atmosphere (5% H2/Ar). Well, what is a flame-assisted spray pyrolysis? A flame-assisted spray pyrolysis (FASP) is an aerosol process that shows great promise as a process for continuous production of nanoparticles at high rate and enables us to control the particle size, crystal size, and morphology of nanoparticles by controlling fuel and carrier gas flow rates, concentrations of precursor, and so on.
