Facts about RDX

RDX’s full form is Research Department Explosive and it was developed at the time of World War II.

Chemical name for RDX is cyclotrimethylenetrinitramine.

In the year of 1946 RDX usage came into picture in United States.

RDX properties include

  • Hard
  • White crystalline solid
  • Insoluble in water
  • Slightly soluble in some solvents

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

Facts about HMX

Octogen is the other name for HMX

HMX stands for

  • High Melting explosive
  • Her Majesty's explosive
  • High-velocity Military explosive
  • High-Molecular-weight rdX

As name mentioned octogen its structure is a eight-membered ring

It was also developed at the time of World War II

HMX is usually used for

  • To implode fissionable material in nuclear devices
  • As a component of plastic-bonded explosives
  • As a component of rocket propellant
  • As a high explosive buster charge

It has advantage in high density of charges that provides for a higher rate of detonation, respectively more efficient application
