Abstract
Gas-generating pyrotechnic solid objects, the composition of which, free of binder and of explosive ingredient, expressed as weight percentages, contains from 35 to 50%, advantageously from 40 to 50%, of guanidine nitrate, from 35 to 50% of basic copper nitrate, from 0.5 to 6% of at least one compound chosen from alumina and inorganic titanates, the melting point of which is above 2100 K, and from 5 to 18% of at least one inorganic oxalate, chosen from sodium oxalate, tin oxalate, strontium oxalate, iron oxalate, copper oxalate and mixtures thereof.
