In technical processes, nanoparticles are mostly present as agglomerates significantly influencing their physical and chemical properties. In this contribution, description concepts for the ramified structures of the agglomerates are outlined and methods to determine the structural parameters of the agglomerates are presented. These techniques are then employed to characterize the mechanical and thermal stability of the agglomerates, which is important for the handling of the nanopowders and their applications in high‐temperature environments. Finally, an example of the interference of the agglomerate structure with a fast gas‐phase reaction is given using the hydrogen oxidation on platinum nanoparticle agglomerates as a model system. It turns out that only about one‐third of the total agglomerate surface participates in the reaction.
