Abstract
A primer composition is provided having a primary explosive and an oxidizer system containing at least one tungsten oxide or one tungstate compound. The oxidizer system can by non-hydroscopic and non-toxic. The primer can include reducing agents, sensitizers, binders and gas producing agents. The primer composition generally is applicable to any application or device that employs ignition of a propellant, a fuel, a relay charge, a delay charge, or a booster charge, including, but not limited to, air bag gas generator systems, signaling devices, ejection seats, small, medium or large arms ammunition primers, and the like.
Claims23

- b. from about 15% to about 50% by weight of a oxidizer;
- c. from about 5% to about 30% by weight of a reducing agent;
- d. from 0% to about 30% by weight of a sensitizer;
- e. from 0% to about 25% by weight of a gas producing agent;
- f. from 0% to about 20% by weight of a friction agent;
- g. from 0% to about 10% by weight of a decoppering agent;
- and
- h. from 0% to about 20% by weight of a conductive component.
A priming composition comprising:
- a. from about 15% to about 50% by weight of a percussion-sensitive organic primary explosive compound;
