Abstract A pyrophoric powder made of an alloy of misch metal having a particle size distribution making it particularly suitable for employment in an airborne incendiary device in combination with an organic binder that serves to initiate oxidation and as an oxidizer. Incendiary devices using the powder dispersion exhibit prompt and sure ignition followed by the formation of a clinker with uniform and slow secondary burning properties.
