Explosives and Rocket Propellants

The following uses have been claimed for compounds containing the 1,2,4,5-tetrazine skeleton as herbicides, insecticides, bactericides, as pharmaceuticals, as explosives and rocket propellants, as photographic dyes and additives to photographic layers, as reducing agents, as inhibitors of steel corrosion and as fuel additives. 

ABSTRACT RARDE work on the ignition or initiation of cased explosives and rocket propellants is reviewed. Attention is focussed on criteria to predict the threshold impact velocity for detonation. Critical energy and power concepts are considered. Experiments show that, for thin cases, a critical energy criterion is adequate but clear evidence is provided for a non-shock initiated detonation regime with thicker cases. Existing criteria cannot describe this phenomenon. The need for a quantitative description of hot spot formation and growth is highlighted.
