Abstract
A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.
