What is the most powerful explosive material?

What is the most powerful explosive material?

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.

Why do peroxides explode?

This is because they combine both fuel (carbon) and oxygen in the same compound. Some organic peroxides are dangerously reactive. They can decompose very rapidly or explosively if they are exposed to only slight heat, friction, mechanical shock or contamination with incompatible materials.

What is the most explosive chemical?

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.

What causes the greatest damage in an explosion?

That is the region of traveling shockwave where original traveling shockwave constructively interfered with the shockwave reflected. This reflection occurs mostly from the ground in battle conditions.

What is the difference between a high explosive and a low explosive?

Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". In contrast, some materials are merely combustible or flammable if they burn without exploding.

What is the most widely used low explosive?

Low explosives are explosives with a velocity of detonation less than 1,000 meters per second. the most widely used explosive in the low explosive group. It is a mixture of potassium or sodium nitrate, charcoal and sulfer.

What are examples of low explosives?

Examples include primary explosives such as nitroglycerin that can detonate with little or no stimulus and secondary explosives such as dynamite (trinitrotoluene, TNT) that require a strong shock (from a detonator such as a blasting cap). Low explosives change into gases by burning or combustion.

What is Emulex explosive?

Emulex is explosive material that is a sensitive emulsion explosive with a greyish-yellow paste like texture wrapped in plastic film or rigid paper tube cartridges. It is used in rock blasting in quarry.

What are the two classes of high explosives?

two types: (1) detonating, or high, explosives and (2) deflagrating, or low, explosives.

What is the most obvious post explosion characteristic of a high or contained low explosive?

T/F: The most obvious characteristic of a high or contained low explosive is the presence of a crater at the origin of the blast.

How often are explosive licenses reviewed?

Every explosives license must be reviewed annually by the Garrison Safety Office. c. The license is a locally developed form following the guidelines established in DA PAM 385-64.

What type of explosive is widely used by the military?

Trinitrotoluene. TNT is the most common military explosive.

Is Dynamite a low explosive?

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.

Do explosives contain pork?

Most explosives contain glycerine and/or gelatin which is made from pig fat.

What are the types of explosives?

Explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.

What is a primary explosive?

A primary explosive is an explosive that is extremely sensitive to stimuli such as impact, friction, heat, static electricity, or electromagnetic radiation. Some primary explosives are also known as contact explosives. A relatively small amount of energy is required for initiation.

Which type of explosive is classified into two groups primary and secondary?

Military weapons use high explosives. Gunpowder and ammonium nitrate are low explosives. High explosives may belong to different groups: primary explosives and secondary explosives. Primary explosives are very unstable and rapidly react to shock, friction, and heat.

Is black powder a high explosive?

Gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. Low explosives deflagrate (i.e., burn) at subsonic speeds, whereas high explosives detonate producing a supersonic shockwave.

What is explosive in mining?

Explosives being used in mining. Drill and blast mining is a common method used to break up 'benches' of rock in order to send the smaller pieces of rock containing ore to the processing plant to further separate the valuable ore from the waste rock.

Which of these items are examples of HC 1 hazards?

Examples include Flares, signals, incendiary or illuminating ammunition and other smoke and tear producing devices. H: Article containing both an explosive substance and white phosphorus (1.2H, 1.3H).

How explosive is ether?

Although ether is almost ubiquitous in biological research laboratories, and most workers are aware that it is flammable and should be kept away from open flames, ether's tendency to form explosive compounds upon contact with air is not as well known.

What type of material might explosively decompose if concentrated?

PECs are materials that may oxidize, decompose, polymerize, become contaminated, dry out or destabilize and subsequently become explosive when subjected to heat, light, friction or mechanical shock.

What is a safety fuse and what is it used for?

Such fuses were in use until the 18th century. The commercial and military version of a burning fuse referred to as safety fuse (invented by William Bickford) is a textile tube filled with combustible material and wrapped to prevent external exposure of the burning core.

What produces the violent physical disruption associated with an explosion?

An explosion is the product of chemical reactions accompanied by the sudden, rapid buildup of expanding gas pressure, producing violent physical disruption of the surrounding environment.

Which explosive train propels launches the projectile?

The fuze initiates an explosive train in the projectile causing the projectile to produce the desired effects.

Is propellant A low explosive?

Solid propellants are usually made from low-explosive materials, but may include high-explosive chemical ingredients that are diluted and burned in a controlled way (deflagration) rather than detonation.

Does petroleum ether form peroxides?

Despite its name “petroleum ether” is not an ether. Instead, it is a particular fraction of hydrocarbon distillate. It is thus NOT especially susceptible to peroxide formation.

What are bombs made of?

Atomic bombs are made up of a fissile element, such as uranium, that is enriched in the isotope that can sustain a fission nuclear chain reaction. When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons.

What explosive class is ammunition?

Ammunition is classified as a Division 1.1, 1.2, 1.3, or 1.4 explosive, depending on the degree of hazard.

What is a detonator What is the composition of most detonators?

Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators.

What are the main ingredients in straight dynamite what other substances also are included in modern straight dynamites and what purpose do they serve?

Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. The black powder used in fireworks is one example of a low explosive.

When were explosives first used?

It may never be known with certainty who invented the first explosive, black powder, which is a mixture of saltpetre (potassium nitrate), sulfur, and charcoal (carbon). The consensus is that it originated in China in the 10th century, but that its use there was almost exclusively in fireworks and signals.

Which acronym is used to identify the four components of an IED?

In addition to the container, which can be anything from a shipping envelope to a backpack, briefcase or even a vehicle, there are four components to most IEDs. Remembering them is made easy by using the acronym PIES: Power, Initiator, Explosive and Switch. Power is self-explanatory.

What are military explosives?

Military explosives, which are Organic Energetic Compounds (OECs), might be initiating factors in clusters of warfare related illnesses. Substances such as HMX, RDX and TNT are neurotoxic and are possible human carcinogens. In many clusters of illnesses a link can be defined with explosives.

Which explosion effect includes a positive pressure phase and a negative pressure phase?

Blast-pressure effect includes a positive-pressure phase and a negative-pressure phase.

Which chemical used to make explosives is a common ingredient in some fireworks?

That takes just two main ingredients: an oxygen-rich chemical (known as an oxidizer, like potassium nitrate) and a fuel to burn (sulfur and charcoal are often used).

How explosives are made?

All chemical explosives require a fuel and an oxidizer. Ammonium nitrate provides both, intimately associated in each molecule. The commercial form of explosive uses ammonium nitrate and fuel oil, a combination known in the industry as ANFO. It is simply poured into holes drilled in rock.

How do explosives work?

The explosive material undergoes a rapid chemical reaction, either a combustion or decomposition reaction, when triggered by heat or shock energy from the detonator. In the chemical reaction, compounds break down to form various gases. The concentrated gases are under very high pressure, so they expand rapidly.
