Examples of Military Explosives

A

C4 - Composition 4
HMX - High Melting Explosive
PETN- Pentaerythritol Tetranitrate
RDX- Cyclotrimethylenetrinitramine
Semtex

22
Q

is a plastic explosive substance used in military combat units for demolition.

A

C4 - Composition 4

23
Q

The active component of composition C4 is ____

A

hexahydro-1,3,5-trinitro-1,3,5-triazine, also
known as RDX (Royal Demolition Explosive).

24
Q

It is also known as octogen and cyclotetramethylene-tetranitramine, as well as by other names

A

HMX - High Melting Explosive

25
Q

is used in various kinds of explosives, rocket fuels, and
burster chargers.

A

HMX (Octogen)

26
Q

HMX (Octogen) is an acronym for High Melting Explosive. It is also known as _____

A

octogen and cyclotetramethylene-tetranitramine

27
Q

is a nitrate ester explosive commonly used in commercial detonators.

A

Pentaerythritol tetranitrate (PETN)

28
Q

Although its degradation properties have been studied
extensively, very little information has been collected on its thermal stability in the molten state due to the fact that its melting point is only -20 °C below its onset of decomposition.

A

Pentaerythritol tetranitrate (PETN)

29
Q

is a hard, white crystalline solid, insoluble in water and only slightly soluble in some other solvents.

A

RDX- Cyclotrimethylenetrinitramine

30
Q

Sensitive to percussion, its principal nonmilitary use is in
blasting caps.

A

RDX- Cyclotrimethylenetrinitramine

31
Q

It is often mixed with other substances to decrease its sensitivity.

A

RDX- Cyclotrimethylenetrinitramine

32
Q

is a general-purpose plastic explosive.

A

Semtex

33
Q

It is used in commercial blasting, demolition, and in certain military applications.

A

Semtex

34
Q

became notoriously popular with terrorists because it was, until recently, extremely difficult to detect.

A

Semtex

35
Q

TYPES OF EXPLOSIONS

A
  1. Chemical Explosions
  2. Decomposition Explosions
  3. Deflagration Explosions
  4. Detonation Explosions
  5. Exotic or Nuclear Explosions
36
Q

These explosions occur due to spontaneous chemical reactions.

A

Chemical Explosions

37
Q

When certain substances react, they release a large volume of rapidly expanding gas in an extremely brief period.

A

Chemical Explosions

38
Q

Chemical explosives are widely used in_____

A

engineering applications.

39
Q

, the chemical decomposition of an explosive material occurs.

A

In decomposition explosions

40
Q

This process can take varying durations—ranging from years to mere fractions of a second.

A

decomposition explosions

41
Q

The gradual breakdown of the explosive substance leads to the release of energy in the form of gas.

A

Decomposition Explosions

42
Q

involves the propagation of an aflame front through the explosive material

A

Deflagration

43
Q

occurs at a slower pace.

A

deflagration

44
Q

Common examples of deflagrating explosives include

A

black powder and smokeless powders

45
Q

is a more intense explosive phenomenon

A

Detonation

46
Q

It occurs when the decomposition is propagated by an explosive shock wave.

A

Detonation

47
Q

High explosives like TNT and dynamite fall into this category. They decompose rapidly, generating immense pressure.

A

Detonation Explosion

48
Q

These involve sustained nuclear reactions that release
massive amounts of energy almost instantaneously

A

Nuclear Explosions

49
Q

These are less common but equally powerful.

A

High-Intensity Laser or Electric Arc Explosions

50
Q

Nuclear explosions, in particular, have been studied for various purposes, including potential ____

A

petroleum extraction
