Baradium

Baradium, along with Klaatunium and Niktoite, was one of the most effective explosive compounds known throughout the galaxy. The explosive was particularly suited for powerful hand-held explosive devices like the highly-illegal thermal detonator and starship-mounted explosive ordinance, such as the ubiquitous proton torpedo.

Urban legend has it that baradium was what added the extra "oompf" to the special sauce applied to cheeseburgers.
