Abstract
An improved non-toxic primer which is devoid of metallic oxidizing compounds and of hygroscopic compounds and is comprised of 30-75% by weight of at least two percussion-sensitive compounds selected from a group consisting of a diazo, a triazole, and a tetrazole compound mixed with approximately 10-30% by weight of a suitable propellant, and a frictionator comprised preferably of approximately 12% by weight of calcium silicide and 8% by weight of fine particles of glass. The glass preferably has a particle size of dimensions less than 0.0021'. The primer provides improved propellant ignition, non-toxic ignition products, improved ballistic data, and greatly minimizes misfires.
