Incomplete reactions in nanothermite composites. [PDF]
J Appl Phys, 2017 Exothermic reactions between oxophilic metals and transition/post transition metal-oxides have been well documented owing to their fast reaction time scales (≈10 μs). This article examines the extent of the reaction in nano-aluminum based thermite systems through a forensic inspection of the products formed during reaction.

Group Combustion of Dispersed Spherical Core–Shell Nanothermite Particles
Thermo, 2022 The group combustion characteristics of core–shell nanothermite particles differ from other dispersed solid or liquid fuels. In a core–shell structure, each discrete nanothermite particle can undergo an exothermic reaction as the oxygen atoms in the ...

The initiation temperatures in nanothermite reactions [PDF]
, 2019 An assumption on general regularities and chemical mechanisms of solid-state reactions in nanofilms and nanothermite mixtures is made. It is demonstrated that the moving force of all Al-based nanothermite reactions is the synthesis of the Al2O3 phase with a high negative enthalpy of formation.

Quo Vadis, Nanothermite? A Review of Recent Progress. [PDF]
Materials (Basel), 2022 One of the groups of pyrotechnic compositions is thermite compositions, so-called thermites, which consist of an oxidant, usually in the form of a metal oxide or salt, and a free metal, which is the fuel. A characteristic feature of termite combustion reactions, apart from their extremely high exothermicity, is that they proceed, for the most part, in ...
