Solonite is a highly-dangerous, high-yield non-nuclear explosive used by the Cylons and Colonials.
The Colonials use the explosive to destroy the Ravashol pulsar in the form of an hand-held solonite charge (The Gun on Ice Planet Zero, Part II).
Cylon Raiders loaded with solonite attempt to kamikaze into Galactica, causing major damage to the last battlestar (Fire in Space).
