Obtaining a Granulated High-Porosity Composite Material Containing Nano-Sized Particles of Transition Metals in a Wave of Flameless Combustion of RDX

It is shown that the wave of flameless hotspot combustion of ballasted RDX can propagate in a stable manner in a granulated initial mixture. Under certain conditions, flameless combustion of RDX-containing granulated mixtures can proceed in an oscillatory or ‘‘fountain’’ mode. Based on the process of flameless RDX combustion, a method of single-stage synthesis of high-porosity granules containing nano-sized cobalt or iron particles is developed. The synthesized granulated composite material reveals a comparable catalytic activity in hydrocarbon synthesis by the Fischer–Tropsch method. This material differs from the existing analogs by the absence of pyrophoric properties.
