1,3,5triamino2,4,6trinitrobenzene (TATB) is a widely applied high explosive,which usually needs to be recrystallized for different application requirements. TATB recrystallization methods such as cooling recrystallization and antisolvent crystallization were introduced. Dimethyl sulfoxide (DMSO),sulfolane,concentrated H2SO4 and alkali are commonly used as solvents. By varying stirring rate, cooling rate and antisolvents adding rate,TATB with different crystal shape and different particlesize can be obtained. The crystallization in the process of TATB synthesis and the properties of recrystallized TATB were presented. The effect of solvents on recrystallization and prospect of TATB recrystallization research were discussed also.
