Abstract

The safety detonator comprises electrodes (5a, 5b) connected by a fuse (6), a barrel (16) separating the fuse from an explosive (3), and an insulating tube (7) separating the electrodes so that the electrodes and insulating tube form a plasma torch separated from the explosive by the barrel. The fuse is made of a plasmagenic material that generates a gas with a temperature above 15000 K and an electron density above 1018/cm3 when a current of at least 5000 A is passed through it.
