Sliced crystals of explosive were obtained according to the following process,embedding of explosive crystals inside resin,slicing of resin into pieces,and dissolving of surrounded resin. The sliced crystals of recrystallized spheroidic NTO were prepared and the SEM images were employed for the growth pattern explanation of the spheroidic NTO particles. The sliced crystals of RDX recrystallized respectively in γ-butyrolactone,cyclohexanone and acetone were prepared,the SEM images of all the three crystals showed the tiny cracks and holes. The crystallinity of three RDX crystals samples were compared. The sliced crystals of two expanded ammonium nitrate particles were prepared and the SEM images showed alveolate holes with diameter less than 10 micron inside the sample of good quality and a few holes with diameter round 10 micron inside the reference sample. The sliced crystals-section SEM methods was conferred to provide the microstructures inside the crystals intuitively including micropore,crack,and other disfigurement. The method and intrinsic textures information would be beneficial to the quality evaluation of recrystallization,influences of crystal defects on explosives sensitivity,and sensitizing/desensitizing of explosives particles etc.
