Ultritium

Ultritium is a material often used as an explosive. 

The Dominion's Internment Camp 371 was once an ultritium mining facility. 

In 2374, Benjamin Sisko and his crew used ultritium to destroy a Jem'Hadar ketracel-white facility. The ultritium was placed in a canister and transported to the facility, where the explosive detonated soon after. (,
