Abstract: Nano diamond and boric anhydride were melted together at high temperature and then was mixed with alumina sol solution. Different proportions of hexogeon powder mixed homogeneously to precursor powder were made into blasting charges. Cartridges were detonated and products were collected. XRD and transmission electron microscopy with selected area electron diffraction were used to characterize the obtained detonation products. And BKW calculation program was used to operate special explosive detonation parameters contained Al and B element.The results show that nano diamond-Al₂O₃ full-package structures are found. The polar material compatibility and good dispersion stability are connected to such nano particle. The product generation mechanism is explored. The chemical bonds are broken by temperature and pressure produced by detonation reaction. The droplet is formed of radical B₂O₃-nano diamond, Al₂O₃ after collision. Al₂O₃ is made into a ball at high temperature. And radical B₂O₃-nano diamond is absorbed. More perfect encapsulation structure and bigger nano diamond is produced by more hexogeon.
