Many law enforcement and military personnel employ flash grenades as one method of entering an area containing hostile targets. The flash grenades provide light and sound in order to blind and deafen hostile persons thereby subduing them as safely as possible. The flash powder used in creating the light and sound normally contains potassium perchlorate and aluminum powder. While this mixture produces bright light and a loud sound report, it also produces a significant amount of smoke through the formation of potassium chloride and aluminum oxide. This obscurant smoke can momentarily blind the law enforcement or military personnel as well as hostile targets. It would improve safety to have the loud bang and flash without the obscuring smoke.
Navy scientists have developed a flash grenade which generates a minimal amount of smoke. The device uses zirconium hydride and ceric ammonium nitrate (CAN) with a small amount of binder material. The ignition of this device produces almost no solid particles while maintaining sound and light characteristics of comparable flash-bang grenades. As opposed to other mixtures including aluminum, magnesium and titanium with CAN, this new formulation using zirconium is safer to handle.
- Simple production process includes drying, mixing, evaporation of a solvent, and granulation
- Safer to handle than comparable flash-bang grenades
- US patent 8,002,914 available for license
- Potential for collaboration with Navy researchers
