The nano-MnO2 was prepared by hydrothermal method, and then combined with Al nanoparticles using ultrasonic mixing, forming superthermite Al/MnO2. Its physical phase, composition, morphology and structure were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscope-energy dispersive spectrometry (SEM-EDS). The differential scanning calorimetry (DSC) was employed to evaluate the compatibilities of the superthermite with HMX, RDX, NC, CL-20 and NTO. The results showed that the nano-MnO2 were rod-like structure. In the superthermite system, the globose nano-Al particles attached to the surface of the nano-MnO2 evenly. The superthermite Al/MnO2 had good compatibility with NC. The systems of Al/MnO2 with RDX and HMX was slightly sensitive, CL-20 and NTO were judged to be incompatible.
