“…74-1368) In the FT-IR spectrum of the prepared silver azide as shown in Figure 6. The typical peak of azide ion is observed at 2030 cm À 1 , which is consistent with Ghica's previous report [29], this strongly proves that silver azide can be in-situ prepared using Ag 2 O as the precursor.…”

Silver azide (AgN 3 ) primary explosive was successfully prepared by in-situ reaction with hydrazoic acid (HN 3 ) using micron-scale silver(I) oxide (Ag 2 O) as the precursor. Ag 2 O particles have been synthesized through a facile chemical precipitation method. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) were used to characterize the prepared materials. The effects of reaction time on the mor-phology and phase composition of silver azide were evaluated. Silver azide can be synthesized by in-situ reaction for 12 h. Increasing the azide reaction time is beneficial to the generation of silver azide but has no obvious influence on the morphology. The prepared silver azide micro-charge can be successfully initiated by NiÀ Cr bridge wire and present favourable explosion performance.Keywords: silver azide · in-situ fabrication · silver(I) oxide · primary explosive Figure 6.
