What are the types of explosives?

Types of chemical explosives.

  • Black powder. History of black powder. Manufacture of black powder.
  • Nitroglycerin.
  • Dynamite. Ammonium nitrate. Low-freezing dynamite.
  • Other explosives. Chlorates and perchlorates.
  • Modern high explosives. Ammonium nitrate–fuel oil mixtures.
  • Nitrocellulosic explosives.
  • Blasting caps. Electrical firing.
  • What is a high explosive?

    High explosives consist of materials that typically combine the reacting elements in the same molecule. This allows them to react much faster, and they “detonate.” Detonation involves supersonic shock waves that pass through the material, causing chemistry that happens quite a bit faster than burning.

    What are the most widely used low explosives?

    Consider for instance black powder, the most primitive form of gunpowder and the quintessential low explosive. In black powder, charcoal and sulphur are the fuel, and postassium nitrate (KNO3) is the oxidizing agent.

    What is the strongest explosive?

    PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

    What is the most explosive substance?

    Azidoazide azide
    Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.

    Which explosive has maximum strength?

    Straight Dynamite – Nitroglycerin in an absorbent, with velocities between 10,000 and 20,000 feet per second. This dynamite is the most sensitive of all commercial explosives. The weight strength is the actual percentage of nitroglycerin in the cartridge.

    Is TNT considered a high explosive?

    ❖ TNT is one of the most widely used military high explosives, partly because of its insensitivity to shock and friction. It has been used extensively in the manufacture of explosives since the beginning of the 20th century and is used in military cartridge casings, bombs and grenades (ATSDR 1995; Cal/EPA 2008).

    What was the biggest explosion in history?

    Russia just declassified footage of the moments leading up to the Tsar Bomba blast — the world’s largest nuclear-bomb explosion. The blast was equivalent to 50 megatons of TNT, making it nearly 1,500 times more powerful than the Hiroshima and Nagasaki bombs combined.

    Why is antimony so explosive?

    Electrolytic deposition of antimony under certain conditions produces an unstable, amorphous form called “explosive antimony,” because, when bent or scratched, it will change in a mildly explosive manner to the more stable, metallic form.
