The long-term use of lead-based primaries has created significant environmental and health hazards, leading to a "holy grail" search for "green" or heavy-metal-free alternatives.
): Extensively used in the 19th century, this compound was one of the first practical primary explosives, famously used by Alfred Nobel in his detonators, but it is highly toxic and expensive. Lead Azide (
and moisture to form hydrazoic acid, which in turn reacts with copper to form the extremely sensitive and lethal copper azide.
A heavy-metal-free compound, though it sometimes suffers from poor performance in extreme cold.
Recent advances include organic compounds such as 6-azido-8H-tetrazolo[1, 5-b][1, 2, 3]triazolo[4, 5-d]pyridazine. 4. Safety Considerations
