Pyrotechnic compositions

Abstract

A priming mix composition includes between about 30% and about 60% of at least one of KDNBF, dinol, and tetrazene as a primary explosive; between about 10% and about 35% of a metallocene as a propagation aid; between about 5% and about 40% of at least one nitrate, peroxide, or oxide, as an oxidizer; between about 5% and about 25% of at least one of nitrocellulose or PETN as a reactive fuel; and a fuel. The metallocene is preferable ferrocene.
