Overview

Molybdenitethe principal ore from which molybdenum is now extractedwas previously known as molybdena. Molybdena was confused with and often utilized as though it were graphite. Like graphite, molybdenite can be used to blacken a surface or as a solid lubricant. Even when molybdena was distinguishable from graphite, it was still confused with the common lead ore PbS (now called galena); the name comes from Ancient Greek molybdos, meaning lead. (The Greek word itself has been
