Tertiary explosives, also called blasting agents, are so insensitive to shock that they cannot be reliably detonated by practical quantities of primary explosive, and instead require an intermediate explosive booster of secondary explosive. These are often used for safety and the typically lower costs of material and handling.
Xylitol pentanitrate (XPN) is a nitrated ester primary explosive [3] [4] first synthesized in 1891 by Gabriel Bertrand. [5] [6] Law enforcement has taken an interest in XPN along with erythritol tetranitrate (ETN) and pentaerythritol tetranitrate (PETN) due to their ease of synthesis, which makes them accessible to amateur chemists and terrorists.
Mercury(II) fulminate, or Hg(CNO) 2, is a primary explosive. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and detonators. Mercury(II) cyanate, though its chemical formula is identical, has a different atomic arrangement, making the cyanate and fulminate anionic isomers.
It is a primary explosive. It has been considered as an initiating explosive for blasting caps in the early part of 20th century, mostly because of its high initiating power (higher than that of mercury fulminate) and its inexpensive production. As such, it was quickly taken up as a primary explosive in mining applications. [1]
Cyanogen azide is a primary explosive, although it is far too unstable for practical use as an explosive and is extremely dangerous outside dilute solution. [7] [8] Its use in chemistry has been as a reagent prepared in situ for use in the synthesis of chemicals such as diaminotetrazoles, either in dilute solution or as a gas at reduced pressure.
Acetone peroxide (/ æ s ə ˈ t ə ʊ n p ɛr ˈ ɒ k s aɪ d / ⓘ also called APEX and mother of Satan [3] [4]) is an organic peroxide and a primary explosive. It is produced by the reaction of acetone and hydrogen peroxide to yield a mixture of linear monomer and cyclic dimer, trimer, and tetramer forms. The monomer is dimethyldioxirane.
Nickel hydrazine nitrate (NHN), (chemical formula: [Ni(N 2 H 4) 3](NO 3) 2 is an energetic material having explosive properties in between that of primary explosive and a secondary explosive. [1] It is a salt of a coordination compound of nickel with a reaction equation of 3N 2 H 4 ·H 2 O + Ni(NO 3) 2 →〔Ni(N 2 H 4) 3 〕(NO 3) 2 ＋ 3H 2 O [2]
TATB, triaminotrinitrobenzene or 2,4,6-triamino-1,3,5-trinitrobenzene is an aromatic explosive, based on the basic six-carbon benzene ring structure with three nitro functional groups (NO 2) and three amine (NH 2) groups attached, alternating around the ring.
