  PETN
 

Pentaerythritol Tetranitrate (PETN) is a white color crystallite material. The crystals are short and Hexagonal with minimum elongates and free from needle shaped crystals, dust and visible impurities. PETN is used independently as a high explosive, as the explosive core for detonating Fuse (or) as an ingredient of composite explosives.

The most common use of PETN is as an explosive with high brisance. It is more difficult to detonate than primary explosives, so dropping or igniting it will typically not cause an explosion (at atmospheric pressure it is difficult to ignite and burns relatively slowly), but is more sensitive to shock and friction than other secondary explosives such as TNT or tetryl. Under certain conditions a deflagration to detonation transition can occur.

It is rarely used alone, but primarily used in booster and bursting charges of small caliber ammunition, in upper charges of detonators in some land mines and shells, and as the explosive core of detonation cord.PETN is the least stable of the common military explosives, but can be stored without significant deterioration for longer than nitroglycerin or nitrocellulose.
