(1) TNT
That is, trinitrotoluene, light yellow crystal, weak hygroscopicity, insoluble in water, good thermal stability, does not decompose at room temperature, and decomposes significantly at 180 °C. TNT's explosion heat 4229kJ·kg-1, detonation speed 6850m·s-1, explosion force 285~300mL, violent 19.9mm, low mechanical sensitivity. TNT is mainly used as a sensitizer for ammonium nitrate explosives. It is an important military explosive for use alone.
(2) Hessian Today (RDX)
Hessian today (also translated as black gold ), ring dimethylene trinitramine, white crystal, not hygroscopic, insoluble in water. Long-term storage below 50 °C does not decompose; mechanical sensitivity is higher than TNT, when the density is 1.66g·cm-3, its explosive force is 520mL, the intensity is 16mm, and the detonation speed is 8300m·s-1. Because of its high explosive force, violentness and detonation speed, the sensitivity is appropriate, and it is commonly used as a core of the detonating cord and a reinforcing agent in the detonator.
(3) Te Quer
Trinitrobenzidine, light yellow crystal, hardly soluble in water, easy to react with ammonium nitrate to release heat, resulting in spontaneous combustion, high thermal sensitivity and mechanical sensitivity, good explosive performance, explosive force 475mL, and a sharpness of 22mm. Often used as a booster for detonators.
(4) Taian (PETN)
Pentaerythritol tetranitrate, colorless crystal, insoluble in water. When the density is 1.74g·cm-3, the explosion heat is 6225kJ·kg-1, the explosion power is high, the detonation speed is 8400m·s-1, the explosion force is 500mL, and the intensity is 15mm.
(5) Ray mercury
Mercury Hg(CNO)2, white or off-white fine crystal, decomposes at 50 °C or above, explodes at 160-165 °C, is extremely sensitive to impact, friction and spark, and has lower sensitivity after damp or pressing, and is easy to chemical with aluminum . reaction. Often used as a detonating agent for detonators ( copper or paper).
(6) Lead nitride
Lead nitride Pb(N3)2, usually white needle crystal, has lower thermal sensitivity than thunder mercury, but has a large explosive power and does not lose its explosive capacity due to moisture, but it is easy to chemically react with copper to form extremely sensitive copper nitride. .
(7) Dinitrodiazophenol (DDNP)
Dinitrodiazophenol, yellow or yellow-brown crystal, good stability, long-term storage in water does not reduce its explosive properties, begins to decompose at 75 ° C when dry, explosion at 170 ~ 175 ° C, impact, friction sensitivity than mercury, The lead nitride is low and the thermal sensitivity is somewhere in between.
