About Molybdenum
Essential trace element involved in several important enzymes. Has the highest melting point of any element that is not a refractory metal at 2,623C. Used in steel alloys for strength at high temperatures. Molybdenum disulfide is a common lubricant. The name means lead in Greek, because it was confused with lead ores.
