In situ fabrication of silver azide micro-charge is investigated. Chemical precipitation method is employed to synthesize silver oxide nanoparticles. Silver azide is successfully fabricated by gas and solid phase in situ method using silver oxide nanoparticles as precursors. The effects of azidereacton time on microstructure and composition of silver azide are evaluated. Results show that silver azide is gradually synthesized in 1 h and that the increasing reaction time can promote the conversion of silver oxide nanoparticles to silver azide. Furthermore, the probe method is employed to measure the average velocity of flyer driven by silver azide micro-charge. Silver azide can be ignited by the Ni-Cr bridge wire and the average velocity of flyer is 2328 m·s-1 . Due to its excellent detonation ability and thermal stability, silver azide micro-charge has a favorable application prospect in MEMS.
