纳米 CoFe2 O4与 Al/CoFe2 O4的制备及对RDX 热分解性能的影响
Preparation of Nano-CoFe2 O4,Al/CoFe2 O4 and Their Effects on Thermal Decomposition Performance of RDX
摘要
Abstract
Nanoparticle CoFe2 O4 and Al/CoFe2 O4 were prepared by hydrothermal method and ultrasonic mixing method,respectively.Their composition and morphology features were measured using X-ray diffraction (XRD)and Scanning Electron Microscope-Energy Dispersive Spectrometry (SEM-EDS).CoFe2 O4/RDX and Al/CoFe2 O4/RDX,according to the mass ratio of 1∶4,were prepared by ultrasonic mixing method.The effects of CoFe2 O4 and Al/CoFe2 O4 on the thermal decomposition of RDX were investigated by a differential scanning calorimetry (DSC). The results show that the addition of nano CoFe2 O4 and Al/CoFe2 O4 does not change the most probable mechanism function of the decomposition process of RDX.While after CoFe2 O4 and Al/CoFe2 O4 being added,the peak temper-ature of the thermal decomposition for the mixture exhibits a significant decrease.Moreover,the apparent activation energies of the mixed systems of CoFe2 O4/RDX and Al/CoFe2 O4/RDX decrease in comparison with that of RDX, indicating that the addition of CoFe2 O4 and Al/CoFe2 O4 can promote the decomposition of RDX.关键词
