Abstract

Abstract: The explosive properties of tetrasulfur tetranitride, S4 N4, are reviewed and analysed. S4 N4 is an explosive compound with an impact sensitivity comparable to pentaerythritol tetranitrate (PETN) (Ei =4 J) but a friction sensitivity equal or even lower than lead azide (F=0.1–1 N). S4 N4 has primary explosive properties. It has a working capacity greater than silver azide, AgN3, and is capable to initiate TNT. S4 N4 shows an unusual non‐linear density/detonation velocity relationship which is due to different stability regimes of sulfur species present in the Chapman Jouguet zone. S4 N4 is stable, non‐ageing, non‐toxic, insoluble in water and hence an interesting candidate for future lead tricinate replacement. Abstract :
