Triaminotrinitrobenzol (short TATB) is an energetic, aromatic nitro compound, which is distinguished by an extraordinary stability. TATB is a strong and explosive explosive, which is superior and at the same time extremely insensitive in its achievement TNT. The stability of TATB against impact and heat effect is larger than from every other well-known material with comparable power density. TATB is not brought even by the impact with aircraft crashes, fires, explosions or the impact by projectiles from hand-held weapons to the explosion. Because of these safety characteristics TATB is the most important explosive in modern nuclear weapons.
TATB forms yellow, triclinic crystals. The solubility of TATB is small and the recrystallization difficult. The solubility in Dimethylsulfoxid amounts to 0.47 g/L with 21 "°C and 6.8 g/L with 145 "°C.Der value for the education enthalpy lies with = -540 kJ/kg. Detonation speed with maximum density: ~ 8000 m/s. Detonation pressure: 31 GPa friction sensitivity: 350 N sensitivity to impact: 50 N m
The extreme insensitivity of TATB is explained by inter+molecular and intramolekulare hydrogen bonds, which due to the alternating Nitro and amino groups around the benzene ring to be formed.
TATB for the first time 1888 manufactured by Jackson and Wing. Into the 1950-er years in the Naval Ordnance Laboratories (the USA) the excellent stability and insensitivity of TATB one recognized and efficient synthesis procedures with high yield was developed. Into the 1970-er years TATB was examined and characterized particularly in detail in the USA.
TATB becomes despite its high manufacturing costs (100. - "/kg) used, if highest insensitivity, stability and security are particularly important, e.g. in atom bombs ("nuclear warheads") or in ammunition for ships and submarines.
Detonations in explosives on TATB basis run differently than detonations in sensitive explosives as for example LX-10 (95% HMX + 5% Viton compound A binder). Detonations in TATB explosives are fast, but delay-free, and do not show a comparatively broad, three-dimensional reaction zone behind the detonation front. Such not-ideal detonations cannot be computed on the basis of simple theories sufficiently exactly. The use of TATB in weapon systems requires a highly developed understanding of the physics and chemistry of initiation and detonation.
Important explosives with TATB are:
Production and processing of TATB are regulated in Germany by the explosive law.
