Abstract

A non-toxic primer mix in which DBX-1 (copper(I) 5-nitrotetrazole) acts as the primary explosive portion of the primer. Furthermore, in this mix, boron carbide (B4C) replaces the traditional frictionator/fuel, toxic antimony trisulfide. In addition, potassium nitrate replaces the toxic barium nitrate (BaNO3)2) as the oxidizer, providing an ignition flame from the primer in a pyrotechnic reaction. The non-toxic primer therefore embodies a lead-free, barium-free, antimony-free explosive material that can include added fuels, sensitizers, explosives and/or binders.
