Abstract: In this paper, we report the elaboration and the characterization of several kinds of nanothermites made at the French German Research Institute of Saint‑Louis (ISL). Three types of materials are presented herein: tungsten trioxide based nanothermites obtained by physical mixing of this metallic oxide withaluminum nanoparticles; tungsten trioxide based nanothermites elaborated by coating WO3 nanoparticles with aluminum using a chemical process; and molybdenum oxide based nanothermites composed of AlxMoyOz nanostructured phases and aluminum nanoparticles. In the light of these examples, we have identified general trends concerning the structural and reactive behavior of the new materials.

Keywords: nanothermites, tungsten oxide, molybdenum oxide, aluminum coating
