摘要: Thermites can offer vigorously-exothermic self sustained reactions. At nanoscale, reaction rate could be enhanced significantly. The most potential oxidizers for nanothermite applications include ferric oxide and copper oxide. Aluminium, with combustion enthalpy of 32,000 J/g, is concern. Fe2O3 (4.0 nm) CuO (25.2 nm) nanoparticles (NPs) were synthesized via hydrothermal synthesis. Oxide NPs re-dispersed in organic solvent aluminium NPs. developed stoichiometric colloids integrated into TNT. Whereas Fe2O3/Al offered an increase TNT destructive effect by 25%; CuO/Al 35%. significant impact mixture ascribed to low ignition temperature; the boiling temperature resulted Cu metal contribute shock wave. Additionally, nanoscopic high oxygen release at lower temperature. It manifested that the effective thermite propagates maximum was introduced detonation
