Kalran: Tales of the four nations/Depleted Uranium

The standard anti-armor weapon of the Goliath, this substance's high density lets it punch through armor easily. This substance is created by separating the still useless 'enriched' Uranium from the ore, which they are still researching to find use of it. The enriched Uranium is normally buried in the desert or still reseached, with the Goliaths using their resources to crack apart the substance.
