Cover illustration. Flame spray pyrolysis (FSP) allows the direct conversion of organometallic precursor materials into crystalline metal oxide nanoparticle products by relying on consecutive spray formation, precursor evaporation, oxidation, nucleation, and subsequent nanoparticle growth mechanisms based on coagulation, sintering/coalescence, and agglomeration. Gas‐to‐particle process design for FSP is demonstrated by using computational fluid dynamics simulation in combination with population balance models (CFD‐PBM) and by providing thorough validation with experimental multiphase flow and particle diagnostics along the high‐temperature flame trajectory. Understanding the evolution of primary and agglomerate nanoparticle diameters with increasing height above burner (HAB) is key to enable products with tailored size and the development of new flame reactor concepts with laboratory or industrial production rate.
