NON-RUSTING IMPACT IGNITION COMPOSITION Russian patent published in 2021 - IPC C06B41/06 C06B25/32 

FIELD: chemistry.

SUBSTANCE: invention relates to the means of initiation. Noncorrosive impact ignition composition contains 35–40 wt. % of lead trinitroresorzinate, 2–4 wt. % of tetrazene, 30–35 wt. % of barium nitrate, 12–18 wt. % of antimony trisulfide, 3–7 wt. % of pentaerythritol tetranitrate and 5–9 wt. % In the form of metal fuel silicocalcium with a total content of silicon and calcium from 65 to 85 % and a specific surface area of from 500 to 2300 cm²/g.

EFFECT: higher impact sensitivity and energy parameters of the composition, as well as stability of ballistic characteristics of shell cartridges of 8.6 mm calibre fitted by them in the temperature range from plus 60 °C to minus 60 °C.
