RDX, an initialism for Research Department Explosive, is an explosive nitroamine widely used in military and industrial applications. It was developed as an explosive which was more powerful than TNT, and it saw wide use in WWII. RDX is also known as cyclonite, hexogen (particularly in German and German-influenced languages), and T4. Its chemical name is cyclotrimethylenetrinitramine; name variants include cyclotrimethylene-trinitramine and cyclotrimethylene trinitramine.
In its pure, synthesized state RDX is a white, crystalline solid. It is often used in mixtures with other explosives and plasticizers, phlegmatizers or desensitizers. RDX is stable in storage and is considered one of the most powerful and brisant of the military high explosives.
