Problems solved by technology

However, oxygen balance and crystal density are often interrelated, and it is difficult to increase them at the same time, thereby improving the detonation parameters in an all-round way; in addition, although the increase in the enthalpy of formation is conducive to improving the energy level of energetic materials, it often leads to lower thermal stability.

Description

technical field [0001] The invention relates to the field of energetic materials. Specifically, it relates to a series of ethylenediammonium ternary crystalline compounds, a preparation method thereof and an application as an energetic material. Background technique [0002] Energetic material is a kind of compound or mixture that can rapidly undergo its own redox reaction under the stimulation of external energy, and quickly release a large amount of heat and gas, thereby doing work on the surrounding medium. Signal flares of pyrotechnic powder, etc.) and civilian fields (such as fireworks and firecrackers, perforating charges for oil exploration, civil engineering and mining blasting, etc.) have a very wide range of applications, and play an important role in promoting national defense construction and national economic development. [0003] Newly synthesized energetic materials have increased rapidly in the past few decades, especially in organic energetic molecules and ...
