This paper reports on the mechanisms of CuO decomposition and its associated phase transformation into Cu2O, as a fundamental step of thermite materials reaction, where CuO serves as the oxidizer. Frenkel pair defects in perfect bulk CuO show extremely high formation energy (>4 eV) indicating that its decomposition initiates at...

This paper describes a kinetic model dedicated to thermite nanopowder combustion,in which core equations are based on condensed phase mechanisms only. We explore all combinations of fuels/oxidizers, namely Al, Zr, B/CuO, Fe2O3, WO3, and Pb3O4, with 60 % of thetheoretical maximum density packing, at which condensed phase mechanisms govern the...

Energetic materials are the only attractive sources of " dormant " energy, enjoying long shelf life (decades), that can deliver quick on-demand bursts of energy in the form of heat and/or pressure. Among the large variety of energetic materials, reactive nanocomposites, based on exothermic thermite reactions, have attracted great attention over...
