This study probed the influence of compounds containing NH_n （n=0-4） groups such as ammonium perchlorate （AP）， guanidine nitrate （GN）， nitroguanidine （NQ）， N-methyl-4-nitroaniline （MNA） and cyclotetramethylene-tetranitramine （HMX） on the solidification process and solidification temperature of 2，4-dinitroanisole （DNAN）. The effects of the type of additives and AP content on the solidification temperature of DNAN were disclosed by a DSC and an optical microscope technique. Furthermore， as-calculated solidification linear velocity and the characteristics of dynamic crystallization process were analyzed based on the solidification process of addictive-containing DNAN in thin layer observed by microscope. The influence of the additives on the formability of the DNAN was studied by cross-section images of a Φ20 mm test pieces. In addition， relationships between solidification enthalpy and corresponding temperature of DNAN was studied based on crystallization thermodynamics. Besides， the mechanisms towards the influences of NH_n compounds on DNAN solidification was analyzed and verified. The results showed that an remarkable-increased solidification temperature of DNAN was achieved by the AP， while being slightly influenced by the AP content and other compounds like GN， NQ， MNA and HMX. The lowest solidification line rate of AP containing object with dendrite-like crystallization could be attributed to the elevated solidification temperature. Influenced by crystallization latent heat during the bulk-growth of DNAN， the microstructure of pure DNAN could be demonstrated as columnar blocks while additive-containing counterparts were disclosed as tiny crystallization. Solidified thermodynamic analysis showed that the DNAN solidification enthalpy was positively correlated with the solidification temperature， which is also affected by heterogeneous additive particles on heterogeneous nucleation. The mechanism and verification of the solidification temperature of DNAN in the present paper demonstrated that the additives with NH₄⁺ can significantly improve the solidification temperature of DNAN.
