Lead Free Electric Primer

Abstract

NAWCWD overcame some major obstacles, meeting both the low-temperature firing requirement (-65?F) and AUR action time (less than 4ms). Many reformulations were required to optimize the LFEP composite. To date there has not been a single incident with the current aluminum/molybdenum formulation. This demonstrates that the LFEP can be used with suitable safety guidelines. The final formulation consisted of 76% Al(50nm)/MoO3(45nm), 20% BTATZ, 2% Kel-F, and 2% Carbon Black. A critical parameter for nano aluminum powder stability in air was a passivation oxide thickness of at least 2.7 nm. Al powders with thinner oxide layers aged badly resulting in poor primer performance.
