摘要
利用DMSo／碱重结晶法制备了平均粒径为60岫的纳米级TATB，对纳米TATB的粒度和形貌进行了表征，并对其性能进行了测试。结果表明：产品粒径在30-100nm之间，细化过程没有改变TATB的晶体结构，粒子呈较规则晶体形状；其钢凹值和撞击感度均较原料有所提高，热稳定性较原料有所降低。
The nano-TATB particle was prepared with alkali-acid recrystallization method, whose mean particle diameter is 60nm. Particle size and morphology of product have been analyzed and performances of product have been tested. It can be found that the particle sizes of TATI3 distribute from 50nm to 100nm, crystal structure of TATB has not been changed in the refining process, and particles become a rule crystal shape. Compared with the raw material, its steel dent and impact sensitivity all has been increased, and its thermal stability is reduced.
