What is an example of high explosive?

What is an example of high explosive?

High Explosives – explosive materials that can be caused to detonate by means of a blasting cap. A few examples of high explosives would be boosters, detonators, dynamite, water gels/slurries, and emulsions. Black powder, smokeless powder, safety fuse, and squibs/igniters are classified as low explosives.

What makes an explosive a high explosive?

High explosives are materials that are characterized by a very high rate of reaction, high pressure development, and the presence of a detonation wave. The guideline applies to the following explosives: blasting explosives in bulk or in packaged form, e.g.; ANFO (ammonium nitrate / fuel oil);

What are examples of low explosives?

Examples of Low Explosives include: Black Powder, Smokeless Powder, and Flash Powder.

What are the different 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 high and low explosives?

Explosive materials may be categorized by the speed at which they expand. 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”.

What is the difference between low explosives and high explosives quizlet?

What is the difference between low explosives and high explosives? Low explosives are explosives with a velocity of detonation less than 1,000 meters per second. High explosives are an explosive with a velocity of detonation greater than 1,000 meters per second.

What are high and low explosives?

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 are the most widely used low explosives?

The most widely used explosives in the low-explosive group are black powder and smokeless powder. Black powder is a mixture of potassium or sodium nitrate, charcoal, and sulfur. Smokeless powder consists of nitrated cotton (nitrocellulose) or nitroglycerin and nitrocellulose.

Is gunpowder a low explosive?

Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn) at subsonic speeds, whereas high explosives detonate producing a supersonic shockwave.

What are the two classes of high explosives What are the differences between the two classes?

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.

What are the characteristics of a low explosive?

Low Explosives: Low explosives deflagrate rather than detonate. Their reaction velocities are 2000 to less than 3000 feet per second. Black powder is a good example. These materials normally have little water resistance, are highly flammable, sensitive to a No.

What does TNT stand for?

Trinitrotoluene
TNT/Full name

What are some examples of low explosives?

Low explosive. The simplest and oldest bombs store energy in the form of a low explosive. Black powder is an example of a low explosive. Low explosives typically consist of a mixture of an oxidizing salt, such as potassium nitrate (saltpeter), with solid fuel, such as charcoal or aluminium powder.

What is the definition of high order explosive?

A high order detonation is generally an ordnance detonation that results in an explosive ordnance producing a designed/intended explosive yield. A low order detonation is generally a controlled ordnance detonation or a malfunctioned ordnance detonation that results in a significantly lower yield than designed.

How are explosive classified?

An explosive is classified as a low or high explosive according to its rate of combustion: low explosives burn rapidly (or deflagrate ), while high explosives detonate. While these definitions are distinct, the problem of precisely measuring rapid decomposition makes practical classification of explosives difficult.
