Thermites are energetic materials which are made of a metallic oxide mixed with a reducing metal1. The reactivity of classical thermites is moderate but it can be substantially improved when micron-sized particles are replaced by nanoparticles. In this paper, three examples of nanothermites are given in order to illustrate the contribution of these nanomaterials in the future spatial and defence applications: - the incidence of the size of the metallic oxide particles on the reactivity was illustrated by the case of WO3/Al nanothermites, - the correlation between the composition/structure of the oxide phase and the reactivity was achieved on AlxMoyOz/Al nanothermites, - the fabrication of Gas Generating Nanothermites was performed by adding military explosives in porous mineral oxides (Cr2O3; MnO2) used to fabricate nanothermites.
