Abstract
A detonator comprising a case into which is inserted a quantity of an explosive composition, a semiconductor bridge positioned adjacent one end of the explosive composition which is electrically connected to a spark gap and in some embodiments a capacitor and a bleeder resistor. A pair of electrically conductive wires are connected to the spark gap and semiconductor bridge to provide a means for passing an electrical charge to the semiconductor bridge. The detonator also may include an r.function. attenuator, such as a ferrite bead, through which the electrically conductive wires pass. The ends of the detonator case are sealed by any appropriate means.

An electrical detonator comprising:
- a casing;
- an explosive composition comprising at least one member selected from the group of hexanitrostilbene, cyclotetramethylene tetranitramine, bis(picrylamino) trinitropyridine and trinitrotrimethylenetriamine contained within said casing;
- a semiconductor bridge positioned adjacent said explosive composition and in intimate contact with a quantity of titanium subhydride potassium perchlorate or 2-(5-cyanotetrazolato)pentaaminecobalt (III) perchlorate;
- a spark gap electrically connected to said semiconductor bridge;
- and
- a pair of electrically conductive wires which penetrate said casing and connect to said spark gap and semiconductor bridge to provide a means of introducing an electrical charge into said semiconductor bridge.
