Promethium is a metal alloy, known for being almost indestructible.
History[]
Bruce Wayne used depleted promethium and reinforced steel to build a sensory deprivation tank for meditation. The promethium-based tank was later used by Koriand'r after Gar Logan recommended the idea from Dick Grayson, believing that it could help subdue her powers while investigating her frequent blackouts. However, Kori was able to escape from the tank.[1]
