Abstract

Due to high reaction activity and high combustion heat release, magnesium is widelyused in the field of explosives. The research focus of this article is the effect of magnesium powdersize and content on the thermal decomposition of PTFE. Two different particle sizes of magnesiumpowder are regarded as research objects. The thermal behavior of Mg/PTFE energetic system wasinvestigated by TG-DSC analyzer. The experimental results show that magnesium has a catalyticeffect on the thermal decomposition of PTFE. With the increase of magnesium content, thedecomposition peak temperature of PTFE decreased firstly and when passed the ratio 50%increased, the best mixing ratio is Mg: PTFE =50:50. Within nano powder, the activation energy ofPTFE decreased by 150kJ·mol-1 compared to 112 kJ·mol-1 by mixing with micro powder. Obviouslynano powder has a better reactivity than micro powder, so has a more obvious catalytic effect.
