Voltarium
From AndroWiki
Voltarium is an artificial, radioactive and very heavy element, which forms the main basis of theNovabombs carried utilised by the High Guard.
Just as well, the Voltarium causes a awkward feeling, which was so highly distinctive at Trance, that it was impossible for her to walk anymore at the view on the Voltarium factory in Baal on Marduk. (3x06)
