ABSTRAKT

Submicron 3,3'-diamino-4,4'-azoxyfurazan [(DAOAF) C4H4N8O3] particles were prepared by means of the high-pressure jet-assisted precipitation method. The physical and chemical properties of the submicron DAOAF particles were characterized by the following methods: Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), particle size analysis, and X-ray diffraction (XRD). The thermal and mechanical safety properties of the samples were also investigated. The results of the SEM and particle size analysis showed that the particle size of submicron DAOAF particles that are nearly spherical in shape range from 100 to 300 nm. The FTIR and XRD results showed that this experiment did not change the chemical and crystal structure of DAOAF. Compared with the raw DAOAF particles, the exothermic decomposition peak temperature of the submicron DAOAF particles increased at different heating rates. The results of mechanical sensitivity analysis showed that both the raw and submicron DAOAF particles were insensitive.
