Overview. Molybdenum was one of the first metals to be discovered by a modern chemist. It is used primarily to make alloys with other metals. The most common ore of molybdenum is called molybdenite. Its melting point is about 2,610°C about 4,700°F and the boiling point is 4,800 to 5,560°C 8,600 to 10,000°F.
