Abstract: The present application belongs to the field of compounds, and particularly relates to the perovskite-type compound ABX3. As a finding of the present application, the structural characteristics of the perovskite type enables the type of compound to be highly stable, thus overcoming the unsafety of an explosive having poor stability in the prior art. Meanwhile, the structural characteristics of the compound, such as rich energetic ligands, as well as the alternately arranged oxidizing energetic anions and reducing organic cations in the space, endow the compound with excellent performance on instantaneously releasing energy at detonation. The resulting three-dimensional structure allows the compound to not only have an energetic material effect but also overcome shortcomings of some existing energetic materials.
