Explosive Compound: Grain Size 20-50 microns

Component Specifications

Definition

A specialized explosive compound engineered for use in precision percussion primer cups, designed to provide consistent, reliable ignition through controlled deflagration or detonation when subjected to mechanical impact or electrical stimulus. This compound is formulated to meet strict sensitivity, stability, and output energy requirements for industrial percussion applications.

Working Principle

The explosive compound functions through rapid exothermic chemical decomposition (deflagration or low-order detonation) initiated by mechanical impact from a firing pin or electrical stimulus. This reaction generates high-pressure gas and thermal energy that ignites secondary charges or initiates mechanical processes in percussion systems.

Materials

Typically composed of lead styphnate (primary), tetracene (sensitizer), barium nitrate (oxidizer), and antimony sulfide (fuel) in precise formulations. May include modern lead-free alternatives like DDNP (diazodinitrophenol) or other organic peroxides for environmental compliance.
