Abstract

Den foreliggende oppfinnelse tilveiebringer pyrotekniske korn med sammensetning omfattende i det minste én oksiderende ladning og i det minste én reduserende ladning og ikke noe bindemiddel. På karakteristisk måte er de nevnte korn i form av hovedsakelig sylindriske blokker: med en tykkelse på mer enn 5 mm; med en ekvivalent diameter på 10 mm eller mer; og med en porøsitet i området 1 til 8 %, grenser inkludert. De nevnte korn, fordelaktig basert på guanidinnitrat og basisk koppernitrat, er egnet for den sakte, lavtrykksgenerering av gass i en forlenget tidsperiodeThe present invention provides pyrotechnic grains of composition comprising at least one oxidizing charge and at least one reducing charge and no binder. Typically, said grains are in the form of mainly cylindrical blocks: having a thickness greater than 5 mm; having an equivalent diameter of 10 mm or more; and with a porosity in the range of 1 to 8%, limits included. The grains mentioned, advantageously based on guanidine nitrate and basic copper nitrate, are suitable for the slow, low pressure generation of gas for an extended period of time.
