Detonation synthesis of metal nanoparticles and study of their morphology

The influence of the characteristics of explosive composites based on PETN and RDX containing Fe(II) oxalate and Cu(II) oxalate and acetate on the morphology of metal-containing nanoparticles formed as a result of detonation was studied using structural analysis methods. It was shown that the composition of the decomposition products of Fe(II) oxalate under explosion conditions is similar to the composition of the products of its thermal decomposition. In contrast, metallic copper and Cu(II) oxide, which are formed during their thermal decomposition, are absent among the decomposition products of Cu(II) oxalate and acetate. For charges containing an additive of Fe(II) oxalate, it was found that the charge density has a stronger effect on the average size of iron-containing nanoparticles and their size distribution than the mass fraction of the additive.
