IGNITING PYROTECHNIC COMPOSITION Russian patent published in 2019 - IPC C06B33/00 C06B27/00 

FIELD: technological processes; imploding works.

SUBSTANCE: invention relates to pyrotechnic malogas flammable composition, which can be used for ignition of working charge enclosed in metal shell, during induction heating of ignition and working charges containing metal structures. Igniter composition contains, wt%: lead dioxide is 77.9–87.2 as oxidant, aluminum powder 9.0–12.9 and sulfur powder 1.3–10.8 as combustible. Invention is aimed at reduction of ignition temperature in conditions of kinetic heating, reduction of specific gas release and increase of specific calorie content.

EFFECT: composition has an ignition temperature of less than 200 °C under conditions of kinetic heating, namely 157–198 °C, gas emission 14,9–30,7 cm³/g and high specific caloric content of 2,120–2,740 J/g.
