plant (with CCI primers because Federal can't make MIL-SPEC lead styphnate
and FA956 mix) then shipped the cartridges to LCAAP (bulk packed) to be linked with LC Tracer and packed out for delivery.
Soon the T53 was replaced with the modern non-corrosive lead styphnate
mix and designated FA 36 in 1958.
Most primers used in North America consist of lead styphnate
(Pb) as an initiating explosive, barium nitrate (Ba) as an oxidizer, and antimony sulfide (Sb) as a fuel; therefore, a combination of these elements in a single particle proves very significant.
Liverpool Crown Court heard that Mrs Wilkins was working with lead styphnate
, a sensitive primary explosive, on March 2, 2005 when she was killed.
The original caps used chlorate of potash with fulminate of mercury, but most modern primers use lead azide, potassium per-chlorate or lead styphnate
Seventy-seven machine guns dwindled to four, and the unstable lead azide was transformed into lead styphnate
, then lead picrate, a less dangerous compound.
The particles of lead strewn about by conventional primers, which have lead styphnate
in them, are considered a health hazard, and OSHA will soon require lead-free primers.
Bullets fly from guns with a bang following the ignition of "primer" material containing lead styphnate
Initiating Explosives II-20 Lead Azide II-20 Lead Styphnate
II-21 Mercury Fulminate II-21 Tetracene II-21 B.
We tend to think lead comes only from the bullet, but in fact the biggest risk to the shooter comes from lead styphnate
, which for decades has been used in primers.
Offices and lunchrooms, a chemistry lab, chemical storage, tetracene manufacture, lead styphnate
manufacture, styphnic acid manufacture, chemical mixing facilities and a waste treatment center are widely scattered.
Individual micro-electromechanical system (MEMS) thrusters, each a poppy seed-sized cell fueled with lead styphnate
propellant, fired more than 20 times at 1-second intervals during the test staged at the White Sands Missile Range.
