Abstract

A lead-free primer energetic composition including Cyanuric Triazide (60%), Tetracene (5%), Barium Nitrate (20%) and Antimony Trisulfide (15%) is produced. The lead-free primer energetic composition is used to construct a primary detonator including a transfer charge of Cyanuric Triazide, which produces a further initiation train that may subsequently detonate a secondary explosive, i.e., HDX, RDX, or a pyrotechnic device.
