The present invention relates to a dry process for the manufacture of pyrotechnic objects from at least one reducing charge selected from guanidine derivatives, metal hydrides, alkali metal hydrides and alkaline earth metal hydrides, and at least one oxidizing charge selected from alkali metal nitrates, alkaline earth metal nitrates and basic metal nitrates, at least one of said reducing and oxidizing charges having the property of flowing under stress. Said process makes it possible to obtain pellets and small tablets directly by compaction/compression, to obtain granules, usable as such, by compaction and then granulation, and to obtain compressed objects by compaction, granulation and then compression.The high-performance pyrotechnic objects obtained constitute a further subject of the invention.
