The Influence of Preparation Method on the Particle Structure of Ultrafine TATB

The ultrafine TATB was prepared by several methods and its particlesize, particlesize distribution, particle shape, pore volume and porosity destribution were also charaterized in the paper. The result indicate that the size of more than 97% particles for submicron TATB sample is inferior to 0.2 μm. The particles prepared by gaspulverizing and synthesizing method were spherical with wide particlesize destribution, nonuniform size and a dint on the surface. The particles prepared by recrystallizing method were sticklike, uniform and narrow particlesize destribution. Freezing dry was beneficial for lightening the congregation of particles.
