Notizen:
During the past few years, a pilot-scale spray pyrolysis set-up able to produce largequantities of submicronic powders (1kg/day) has been assembled in our laboratory. Duringthe process, droplets of a precursor solution are dried and decomposed to the requiredcompound.The presence of an additional soluble flux in the precursor solution permits to obtainagglomerate - free nanoparticles after washing the product. Therefore, pure zinc oxidenanoparticles have been successfully synthesized by adding lithium or sodium nitrates to theinitial zinc nitrate solution. The nanoparticles have been characterized by X-ray diffraction,field-emission scanning electron microscopy, laser scattering size analyzer. The influence ofthe precursor solution composition and of the operating parameters on the morphology andthe average size of ZnO nanoparticles is discussed
