Primary Explosives Today

A heavy-metal-free compound, though it sometimes suffers from poor performance in extreme cold.

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. Primary Explosives

): Frequently used in percussion primers due to its high sensitivity to fire and electrostatic discharge. 3. The "Holy Grail": Green Primary Explosives forming part of detonators

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

Initiate less sensitive secondary explosives, which are safer to handle but hard to light. 2. Legacy Primary Explosives

Primary explosives are typically used in milligram quantities, forming part of detonators, primers, and blasting caps. They are designed to possess a rapid transition from deflagration (burning) to detonation (DDT).

A potassium-based green alternative used in some civilian applications.
