Cyclotrimethylenetrinitramine (RDX)
Also referred to as cyclonite, or hexogen, RDX is a white crystalline solid usually used in mixtures with other explosives, oils, or waxes; it is rarely used alone. It has a high degree of stability in storage and is considered the most powerful and brisant of the military high explosives. RDX compositions are mixtures of RDX, other explosive ingredients, and desensitizers or plasticizers. Incorporated with other explosives or inert material at the manufacturing plants, RDX forms the base for the following common military explosives: Composition A, composition B, composition C, HBX, H-6 and Cyclotol.
