Molybdenum. The metal is silvery white, very hard transition metal, but is softer and more ductile than tungsten.Scheele discovered it in 1778. It was often confused with graphite and lead ore. It has a high elastic modulus, and only tungsten and tantalum, of the more readily available metals, have higher melting points.Molybdenum has one of the highest melting points of all pure elements.

How was Molybdenum discovered? | History of Molybdenum
Since molybdenum is easily oxidized and has high brittleness, molybdenum smelting and processing are limited. Molybdenum was not able to be machined in the early period, so it is impossible to apply molybdenum to industrial production on a large scale. At that time, only a few molybdenum compounds were used.
