Abstract
A Flame Spray Pyrolysis reactor has been commissioned at Argonne National Laboratory for research in materials synthesis. The system features a closed combustion environment with full control of all combustion gases and liquids and includes a high-temperature-residence-time section for post-flame in-situ annealing. The system includes in-situ particle and flame diagnostics: PLIF (planar laser induced fluorescence) and SMPS (scanning mobility particle sizing). The PLIF instrument has been configured to provide FRS (filtered rayleigh scattering) temperature and multiple species imaging (Fe, FeO, OH, SiO, NO, Fe, CH, Li). In addition, combustion solid particles are collected before and after the HTRT section for TEM, and advanced synchrotron diagnostics (PDF-SAXS-WAXS). The system has been deployed for the development of Fe-silica catalyst and doped-LLZO for solid state electrolyte applications. We will present preliminary results of the process development demonstrating the use of the in-situ and ex-situ diagnostics for generating useful particles in flame aerosol combustion.
