Title: Method For Producing Metal Particles by Spray Pyrolysis Using a Co-solvent and Apparatus Therefore.

Abstract: Gas-to-particle conversion processes have been used to produce various micro and nanoscale metal powders because of their convenient process characteristics. Recently, hydrogen gas approaches for reducing metal oxides made from metal precursor aerosols in gas-to-particle conversion processes were developed by several research groups. However, aerosol decomposition reactions may be very dangerous at high temperatures due to the explosive potential of hydrogen at high concentrations in the presence of oxygen. This invention is a novel process based on the use of a co-solvent for preparing pure metal nanoparticles under safe conditions in a high-temperature aerosol decomposition reactor. The resulting copper nanoparticles prepared from copper nitrate using a nitrogen carrier gas at 600° C with a 3.3 second resident time are pure. X-ray diffraction is used for measuring particle composition and a transmission electron microscope (TEM) is used for imaging to determine particle morphology.
