摘要:以5-硝胺基四唑和氢氧化钡为原料，合成了二水合5-硝胺基四唑钡（Ba(NAT)(H2O)2），经过高温除水，获得Ba(NAT)无水产物，对该化合物的结构、热分解性能进行表征分析，并对其感度性能、5s爆发点、比容、爆热、起爆性能进行测试。结果表明：与常见起爆药相比，Ba(NAT)具有极强的热稳定性，其对撞击、摩擦、火焰和静电均钝感，且能够起爆耐高温炸药HNS，可以作为耐高温起爆药应用于航空、航天、油田开采等领域。
Abstract:The barium 5-nitriminotetrazolate dihydrate (Ba(NAT)(H2O)2) was synthesized using 5-nitriminotetrazolate and barium hydroxide as raw material, then the primary explosive barium 5-nitriminotetrazolate (Ba(NAT)) was obtained by dehydrating the two molecular waters of Ba(NAT)(H2O)2 under high temperature. The structure and thermal decomposition property were characterized and analyzed, and the sensitivity properties, 5s explosion point, specific volume, explosion heat and initiation performance of Ba(NAT) were tested. Compared with common primary explosives, BA(NAT) has better thermal stability, it is insensitive to impact, friction, flame and static electricity, and can detonate the high temperature resistant explosive HNS, which show it can be used as high temperature resistant primary explosive in aviation, aerospace, oilfield exploitation and other fields.
