Element X is a mineral substance.
It was stored in a secure facility until it was stolen by Vulkanus and Sixsix while being transported. When combined with the Bicenthium Alloy (the alien name for iron ore), it creates an explosive which is powerful enough to obliterate an entire solar system. Element X is useless by itself, however.
According to Synaptak, Element X and Bicenthium alloy can only be bound together with an enormous amount of heat.
As it was revealed in The Ballad of Mr. Baumann, Element X requires careful handling. Contact with iron ore not bounded can create an explosion, and it can injure the user severely. Element X could destroy an entire star system by accident on contact with the metal. It was also revealed that it's rare.
Element X can be used to power certain ships such as Sheelane's.
The mineral both by it's very nature and rarity attracts alien criminals such as the likes of Vulkanus.
