歴史
Molybdenite was often confused for graphite and it was thought to contain lead.
In 1778 Swedish scientist Carl Wilhelm Scheele proved that molybdenite was not graphite nor did it contain lead.
In 1781, Scheele's friend and countryman, Peter J. Hjelm isolated the metal by using carbon and linseed oil.
