Abstract

Pyrotechnic composition intended for the production of delay fuses, of the type consisting of a powder mixture of tungsten, barium chromate and potassium perchlorate, characterised in that it contains an ultrafine silica powder whose particles have a mean diameter of between 7 and 40 millimicrons, according to a mass percentage of the order of 0.5 to 1.5 %, to produce a coating of the powder particles.
