초록

A non-toxic primer mix including both bismuth sulfide and potassium nitrate as the pyrotechnic portion of the primer is disclosed. In a further embodiment, a non-toxic primer mix comprising zinc sulfide and aluminum nitrate as the pyrotechnic portion of the primer mix is disposed. Bismuth and zinc sulfide act as fuels for the oxidizers of potassium and aluminum nitrate in providing an ignition flame for the primer. The non-toxic primer mix further contains a lead-free explosive material, and additionally can include added fuels, sensitizers, explosives a...
