High explosives (HE, or high-order explosives) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity of about 3–9 kilometres per second (9,800–29,500 ft/s).

Detonating explosives, such as TNT and dynamite, are characterized by extremely rapid decomposition and development of high pressure, whereas deflagrating explosives, such as black and smokeless powders, involve merely fast burning and produce relatively low pressures.

Explosives which detonate and propagate at velocities greater than 1000 m/s, are high explosives and include the secondary explosives RDX, HMX, HNS, DIPAM, TETRYL, DATB, TATB, PETN, TNT. PROPERTIES of explosives are measurable physical attributes typical of a single crystal of an explosive material.

What are High Explosives? High Explosives have powerful explosive properties, exploding at a supersonic level. They produce an explosion with a velocity ranging from 3000 to 9000 meters per second. The chemicals that make up high explosives decompose extremely quickly.

Conventional explosives work by rapidly burning to create hot gases at high pressure, which expands to cause an explosion. Manhattan Project scientists used explosives for a counter-intuitive purpose: to do the precision work of assembling the critical mass in the bomb core.

An explosive is a material that, under the influence of thermal or mechanical shock, decomposes rapidly and spontaneously with the evolution of large amounts of heat and gas. There are two major categories, high explosives and low explosives. High explosives are further divided into initiating, or primary, high explosives and secondary high ...

High explosives differ from regular explosives, such as fireworks or gunpowder, primarily in the speed and intensity of their chemical reactions. A high-explosive reaction occurs almost instantaneously after it’s triggered, creating a powerful blast and high-pressure shock waves.

Abstract: This review discusses the recent advances in the syntheses of high explosive energetic materials. Syntheses of some relevant modern primary explosives and secondary high explosives, and the sensitivities and properties of these molecules are provided.

Chemical explosive material having an extremely high reaction rate that creates very high combustion pressures, unlike low explosives that have a much lower reaction rate and are commonly used as propellants. High explosives are further categorized as primary- and secondary-high explosive.
