The non-isothermal crystallizations of 3, 4-dinitrofurzananofuroxan (DNTF), 2, 4, 6-trinitrotoluene (TNT) and DNTF-TNT eutectic system in RDX were investigated by differential scanning calorimeter (DSC). The results show that RDX and hexanitrostibene (HNS) added to DNTF, TNT and DNTF-TNT eutectic system can reduce the 'super-cooling degree' and eliminate heating-self in crystallizations of these systems. The various kinetics models were used to investigate the crystallization behaviors of DNTF,TNT and DNTF-TNT eutectic systems. The crystallization kinetics exponents n were obtained by Avrami equation and the mechanism functions were proposed. Ozawa exponents m were obtained by Avrami-Ozawa equation, and activation energy of non-isothermal crystallization kinetics parameters for DNTF, TNT and DNTF-TNT were obtained to be-378.19, -260.70 and -145.59 kJ·mol-1 respectively by Kissinger.
