Abstract: (1459 Views)

In this work, thermochemical and ignition characteristics of a pyrotechnic compound containing Zirconium and Fe₂O₃ (Zirconium as a metal fuel and Fe₂O₃ as an oxidant) was studied. The influence of the fuel to oxidant ratio on the rate and ignition behavior of the Zr-Fe₂O₃ pyrotechnic system was investigated. Burning rate increases with the increase of fraction of fuel until 60%. Therefore, the delay times of the mixtures were in the order Zr(70)-Fe₂O₃(30)> Zr(50)-Fe₂O₃(50)> Zr(60)-Fe₂O₃(40). On the other side, order of the ignition temperatures of mixtures was Zr(70)-Fe₂O₃(30)> Zr(50)-Fe₂O₃(50)> Zr(60)-Fe₂O₃(40). The obtained Zr-Fe₂O₃ mixtures were thermally stable up to 500ᵒC. Based on the results, the Zr-Fe₂O₃ can be used as pyrotechnic millisecond delays and initiators because of its high combustion rate and heat and acceptable thermal stability.
