摘要
Abstract
Based on the principle of spray recrystallization assisted by ultrasonic,submicron RDX parti-cles were prepared by solvent non-solvent method with different proportions of dimethyl sulfoxide (DM-SO)and N,N-dimethylformamide (DMF)as mixed solvent.The thermal decomposition properties of the RDX particles,which were refined in different proportions of the mixed solvent,were studied by u-sing differential scanning calorimetry (DSC)based on the method of Kissinger.The results show that the apparent activation energy of the RDX is gradually reduced with the increase of DMF in the mixed solvents.When DMF and DMSO ratio is 4:1 ,the refined RDX has the worst thermal stability.关键词
