The study elucidates the influence of three nitrogen-rich explosives viz., FOX-7, FOX-12, and RS-RDX on the performance of B/KNO3/PEC igniter composition. The B/KNO3 pyrotechnic igniter compositions with 5, 10 & 15 parts of FOX-7, FOX-12, and RS-RDX were successfully prepared. The compositions were evaluated in terms of surface morphology, heat output, sensitivities, flame temperature, pressure output, ignition delay, time to reach Pmax (BTPmax), and thermal analysis. The closed vessel firing data indicated higher Pmax value and lower BTPmax for FOX-12 and FOX-7 based composition. The addition of FOX-12 and FOX-7 also reduces the decomposition temperature of B/KNO3 composition without affecting friction and spark sensitivities. The composition having 15 parts RSRDX is the most insensitive to impact among all. Therefore, the addition of insensitive high explosives like RS-RDX, FOX-7and FOX-12 is useful to improve the performance of the igniter composition to achieve low BTPmax and increased pressure output. Optimum performance is exhibited by RS-RDX-based compositions.

富氮炸药对B/KNO3组合物形貌、热学和燃烧行为影响的研究
该研究阐明了三种富氮炸药，即 FOX-7、FOX-12 和 RS-RDX 对 B/KNO 3 /PEC 点火剂组合物性能的影响。成功制备了含有5、10和15份FOX-7、FOX-12和RS-RDX的B/KNO 3烟火点火组合物。根据表面形态、热输出、敏感性、火焰温度、压力输出、点火延迟、达到P max (BTP max )的时间和热分析来评估组合物。密闭容器燃烧数据表明基于 FOX-12 和 FOX-7 的组合物的P最大值较高和 BTP最大值较低。FOX-12和FOX-7的加入也降低了B/KNO 3的分解温度组成而不影响摩擦和火花敏感性。具有 15 份 RSRDX 的组合物对冲击最不敏感。因此，加入RS-RDX、FOX-7和FOX-12等不敏感的高炸药有助于提高点火组合物的性能，以实现低BTP最大值和增加压力输出。基于 RS-RDX 的组合物表现出最佳性能。
