Characterization of 2,6-Diamino-3,5-Dinitropyrazine-1-Oxide (LLM-105) as an Insensitive High Explosive Material
LLM-105 (2,6-diamino-3,5-dinitropyrazine-1-oxide) is a new molecule which has performance and insensitivity between those of HMX and TATB. Its calculated energy content is about 85% that of HMX and 15% more than that of TATB. It is thermally stable, insensitive to shock, spark and friction and has impact insensitivity level approaching that of TATB. These combined properties make it a realistic high-performance IHE material, attractive for applications that require moderate performance and insensitivity. Several morphologies of LLM-105 and plastic-bonded formulations containing these materials and another binder were prepared and characterized. Their physical properties and detonation spreading characteristics are compared to those of ultrafine TATB. The impact sensitivity (drop hammer results) is sensitive to particle morphologies. Detonation-spreading, spot-size tests on LLM-105 compositions showed higher energy output and superior divergence behavior than is observed for ultrafine TATB. The small-scale safety data, pressing characteristics and results from divergence experiments will be summarized.
