Abstract

Thermochemical transformations of potential precursors for nanoparticles of Mn, Cr, and V in the wave of flameless combustion (smoldering) of RDX in ballasted systems were explored. No full reduction to a metallic state was detected. In the wave of flameless combustion, manganese carbonate was found to yield manganese(II) oxide with a particle size of 0.1–0.5 μm; ammonium dichromate, chromium(III) oxide with a particle size of 0.2–0.3 μm; while ammonium vanadate, vanadium(III) oxide in the form of platelets 20–30 nm thick and 0.5–1.0 μm in size at a specific surface of 18.6 m²/g.

无火焰RDX燃烧波中Mn，Cr和V前驱物的还原

摘要

探索了在镇流系统中RDX的无焰燃烧（阴燃）波中Mn，Cr和V纳米颗粒的潜在前体的热化学转化。没有检测到完全还原为金属状态。在无焰燃烧的浪潮中，发现碳酸锰产生的氧化锰（II）的粒径为0.1-0.5μm。重铬酸铵，氧化铬（III），粒度为0.2–0.3μm；钒酸铵是厚度为20–30 nm的血小板形式的氧化钒（III），在18.6 m ² / g的比表面上的大小为0.5–1.0μm 。
