Regulus, The Little King Of Leo

Hedyphane

Varying from white to yellowish with occasional reddish or green specimens, it was named after its discovery in Sweden in 1830 from the Greek words for ‘appearing beautiful’. It is a rare critter, only forming in manganese or zinc ore deposits that have been metamorphosed by heat and pressure deep within the crust, or when intruding granites bake the surrounding rock. It is a part of the apatite group (see http://bit.ly/2akYWkg)and includes lead and calcium combined with arsenic and oxygen in its composition, being an analogue of another pretty mineral called mimetite (see http://on.fb.me/1zo1vvI).

Cyanuric triazide or 2,4,6-triazido-1,3,5-triazine is white crystalline solid when pure and is an organic primary explosive with a detonation velocity of about 7,300 m·s-1. More than enough to remove a few fingers, so don’t even think about making it.

It is a quite interesting compound, since it only contains carbon and nitrogen, 3 carbon and 12 nitrogen in each molecule and 9 of these are in 3 azido groups. The compound is highly shock sensitive, it explodes while grind in a mortar. It has a sharp melting point a bit under 100 °C but it explodes upon heating above 200 °C giving nitrogen and elemental carbon as graphite and maybe some diamonds.

Since this compound is a highly sensitive energetic material I would recommend to do not try it out how this works. On the picture and the gif approx. 40-50 mg (0,04-0,05 g) cyanuric triazide was ignited. Even this small amount could be enough to cause serious damage, injury. 

Anyone want to read short reviews from energetic materials?
