Abstract
The invention belongs to the field of compounds, and particularly relates to a crystalline compound based on hydroxylammonium and/or ion assembly and a solid solution thereof, a preparation method thereof and application thereof as an energetic material, and the crystalline compound is found to have excellent energetic property and practicability when being used as the energetic material. Compared with the prior art such as ammonium ions, the compound has the advantages that the hydroxyl ammonium and the ions have higher enthalpy of formation, and more hydrogen bonds are expected to be formed in crystals for interaction, or higher binding force is favorably obtained, so that the enthalpy of formation and the crystal density of the compound are simultaneously improved. Therefore, the inventor constructs a metal-free energetic material by using the material so as to further improve the energetic characteristic. The at least one compound is high in theoretical explosion heat and volume energy density, excellent in detonation performance, good in safety performance, high in theoretical specific impulse value, free of volatility and capable of being stored for a long time without decomposition; crystallinity is single at room temperature, the raw materials are cheap and easy to obtain, the production process is simple, and safe and large-scale preparation can be realized.
Description
technical field [0001] This application relates to the field of chemical compounds. Specifically, it involves the inclusion of hydroxylammonium ions (NH 3 Oh + )and / or Ions (NH 2 NH 3 + ), their preparation and their use as energetic materials. Background technique [0002] Energetic materials are a type of material that can undergo violent chemical reactions when subjected to external stimuli (such as mechanical force stimuli, thermal stimuli, etc.), rapidly release a large amount of energy (usually accompanied by a large amount of gas and heat) and produce deflagration / explosion phenomena. Material. The rapid energy release of energetic materials plays an important role in both military and civilian fields. For example, in the modern military field, it can not only be used as a power source for military projection devices such as projectile launch and rocket delivery, but also the material basis for military damage. ; In the modern civilian field, it is widely u...
