Abstract

The invention discloses a crystal, a preparation method thereof and application of the crystal as an energetic material, and belongs to the technical field of energetic materials. The molecular formula of the crystal is M3C8H12N34, and M is a metal element and is selected from any one of Mn, Fe, Co, Ni, Cu, Zn and Cd. The M3C8H12N34 provided by the invention has excellent stability and safety, and when the M3C8H12N34 is used as an energetic material, compared with the existing commercial primary explosive lead azide, the required limit explosive dose is 1/2 of the energetic material; compared with the existing commercial initiating explosive nickel hydrazine nitrate, the required limit explosive amount is 1/10, the defects of serious lead pollution and insufficient explosion performance are overcome, and the method has important commercial application value in the field of green high-performance energetic materials.

Description

technical field [0001] The present invention relates to a type of crystal, its preparation method and application as energetic material, and belongs to the technical field of energetic material. Background technique [0002] Energetic materials are mainly used in the fields of detonators, explosives and pyrotechnics. At present, the commercial primary explosives are mainly lead azide Pb(N 3 ) 2 (LA), nickel hydrazine nitrate [Ni(NH)](NO)(NHN), etc. Although these detonators are simple to synthesize, their explosive products have relatively serious heavy metal pollution problems, and they require larger doses when detonating due to insufficient detonation output. [0003] Researchers have developed new lead-free and more explosive primers such as 6-nitro-7-azido-pyrazolo[3,4-d][1,2,3]triazine- 2-oxide (ICM-103), but its synthesis steps are numerous, and there is a great danger, which is not conducive to safe production. [0004] At the same time, with the development of ...
