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.

Lead free detonator and composition

A detonator for a hand grenade fuze comprises a detonator case; a slider that is transversely reciprocable in the detonator case from an unarmed position to an armed position, the slider including a longitudinal through-hole filled with a primary explosive; a spring that biases the slider to the unarmed position; an arming mechanism attached to the slider, the arming mechanism comprising a shape memory alloy; an explosive lead disposed below the slider; and a booster charge disposed below the explosive lead.
