Primary: Explosives

Lead azide can react with atmospheric CO2CO sub 2

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

Remote-operated facilities are often required to manufacture and test these materials to protect personnel. Summary Table: Legacy vs. Green Primaries Legacy Primaries (Lead Azide) Green Primaries (e.g., DBX-1) Toxicity High (Heavy Metal) Low (Environmentally Friendly) Sensitivity High (Controlled) Stability Moderate/Good Good Thermal Stability Replacement Status Lead azide can react with atmospheric CO2CO sub

For over a century, primary explosives have been dominated by heavy metal compounds, primarily mercury and lead. Mercury Fulminate ( A heavy-metal-free compound

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