两种新型高氯酸基钙钛矿含能材料的合成、结构与性能
Synthesis,Structure,and Properties of Two New Perchlorate-Based Perovskite Energetic Materials
摘要
Abstract
As an emerging high-energy substance,the development of perovskite energetic materials in both variety and quantity has more urgency.The first perchlorate-based double perovskite energetic material{(C6H14N2)2[Na(NH4)(ClO4)6]}n(DPE-1)and a single perovskite energetic material[(C4H12N2)K(ClO4)3]n(PAP-2)were synthesized by a solution-based method.The chemical structure,thermal stability,detonation performance,and mechanical sensitivity of both DPE-1 and PAP-2 were system-atically investigated.Single-crystal X-ray diffraction analysis shows that DPE-1 crystallizes in a double perovskite structure with space group Pa-3,while PAP-2 crystallizes in a single perovskite structure with space group Pnma.Compared with the previous-ly reported periodate-based double perovskite energetic material(C6H14N2)2[Na(NH4)(IO4)6]}n(DPPE-1),DPE-1 exhibits signif-icant improvements in the thermal decomposition temperature(Tdec=368.9℃),detonation velocity(D=8858 m·s-1),detona-tion pressure(p=38.4 GPa),impact sensitivity(IS>40 J),and friction sensitivity(FS=20 N).These results validate the feasibili-ty of exploring high-performance,green primary explosives within the double perovskite structural framework.PAP-2 demon-strates comparable thermal stability(Tdec>280℃)and detonation performance(D>8500 m·s-1,p>30 GPa)with other single perovskite energetic materials in the same series,but its impact sensitivity is significantly increased and friction sensitivity is sig-nificantly reduced.关键词
