Provided is an explosive body X, i.e., an explosive body for nanodiamond synthesis, includes at least an explosive main body (10) that includes a frustum part (11) and a columnar part (12). The frustum part (11) includes an upper bottom surface (11a) including an open end of a hole (H), in which a triggering unit is received, and an angled side surface (11b) forming an imaginary apex angle on the upper bottom surface (11a) side. The columnar part (12) is formed contiguous with the frustum part (11) on an opposite side of the frustum part (11) to the upper bottom surface (11a) of the frustum part (11) and extends in a direction away from the upper bottom surface (11a). The explosive body for nanodiamond synthesis is suitable for improving the yield in nanodiamond synthesis by a detonation method.

A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 m particle size.
