Abstract

A conducting composition for detonators having insen­ sitivity to one amp of current or one watt of power con­ sisting of 40 to 80 percent by weight of lead styphnate, 2 to 10 percent by weight of carbon black and/or graphite and the balance lead oxide or other exposive or non-explosive material. Firing times of less than eight milliseconds can be achieved where at least one percent of graphite is included in the composition.
