The non-isothermal crystallization of 3,4-dinitrofurzanfuroxan（DNTF） in RDX was studies by DSC. The results show that RDX reduces the super-cooling degree and eliminate heating-self. On the basis of Avrami and Avrami-Ozawa equations,the Avrami exponent n and Ozawa exponent m are obtained to be 3.12 and 2.48,respectively. The kinetic parameters E_a of DNTF non-isothermal crystallization is obtained by Kissinger equation to be -378.19 kJ·mol^-1. Moreover,the behaviors of non-isothermal crystallization of DNTF in RDX and HMX were compared.
