High modulus, pyrolized polyacrylonitrile (carbon fiber) can be used to drastically enhance CMDB (and likely other types of) propellant burning rates. And carbon black is slightly energetic on its own - coal fires. Other than that, metal fuels are the closest thing to an elemental EM you’ll find.

Ag2BTA


Anyone here with information about the disilver salt of bistetrazolylamine? I found this substance mentioned in "laser ignition of energetic materials" by S Rafi Ahmad and Michael Cartwright 10 years ago:

The copper and silver salt of bis tetrazolyl amine CuBTA (46) and Ag2BTA (47) have been trialled as primary explosives (...) the performance of these materials is a little unpredictable, and they should be treated with extreme care - particulary the silver bistetrazolamine. There is insufficient data in the literature to fully characterize their properties as primer compositions."

I couldn’t find any info on the silver salt, but the 5,5’-bis(tetrazolyl)amine is light sensitive on its own (much less energetic as compared to a detonation).

Laser sensitive EMs are pretty common though, laser initiation systems far less so.

EP 2 679 567 A2


There is an european patent filed in 2012, but the information is pretty sparse.

Impact sensitivity greater than one Joule, friction sensitivity greater than 20 Newton, decomposition temperature 360 degree centigrade (sic!)
Detonation was observed with 200 mW @ 532 nm wavelenght.
The chromium (III) salt is even more thermally stable, but deflagrates only.

The synthesis is also described and easy, so I´ll give it a try next time.
