“…and mixed (LiMn 2 O 4 , MnFe 2 O 4 , SrAl 2 O 4 , etc.) oxides were, thus, synthesized from energetic charges made of RDX or ammonium nitrate (AN, NH 4 NO 3 ) as detonative compounds mixed with metallic salts as ceramic sources [5][6][7][8][9][10][11][12][13][14][15]. More recently, the TNT molecule was offered as an explosive source to synthesize zirconia nanopowder from polymer-coated zirconium sulfate tetra hydrate, and pure silicon carbide (SiC) nanoparticles were prepared by the detonation of a TNT/RDX energetic charge previously mixed with a preceramic polymer (polycarbosilane) [16,17].…”

A detonation process based on 2,4,6 trinitrotoluene (TNT), used as an energetic reagent, was successfully implemented in the synthesis of a series of metal oxide ceramics. TNT offers better physicochemical and mechanical properties than the energetic compounds traditionally used in such processes, thus offering safer handling and transport conditions. The experimental procedure, which consisted to of mixing the energetic molecule with a ceramic salt, was simple to perform. The detonation products were characterized by X-ray diffraction, scanning and transmission electron microscopies, energy dispersive X-ray spectroscopy and nitrogen physisorption. The as-synthesized ceramic powders (CeO2, HfO2, Nb2O5, and In2O3) were crystalline and made of nano-sized quasi-spherical particles. This investigation provides an enhanced detonation synthesis process for elaborating ceramics. The majority of the oxide materials mentioned in this study had never previously been prepared by the detonation process.

Zirconium (IV) oxide nanopowder was successfully synthesized through the detonation of a mixture composed of 2,4,6 trinitrotoluene (TNT, C7H5N306) and zirconium sulfate tetrahydrate (Zr(S04)2•4H20) as the energetic material and ceramic precursor, respectively. TNT, one of the most popular explosives, is a secondary energetic molecule and exhibits high stability and low sensitivity toward extemal stresses, making its handling safe. After detonation of the energetic material/ceramic precursor mixture and purification of the detonation soot, a crystallized zirconium oxide (Zr02) powder composed of nanosized particles with a spherical morphology was produced and analysed by the usual characterization techniques (X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and nitrogen physisorption). The reaction mechanism, con sidering the thermochemical aspect of the explosive, is offered. This approach could provide promising op portunities for the synthesis of various nano-sized oxide ceramic powders.
