molybdenum discovery process

Under natural conditions, there is no metal form molybdenum , and mainly in the form of molybdenite distributed in nature, the average crustal abundance of 1.3 mg / kg. Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal. 18th-century Greeks called galena molyldena, they substantially the same shape and density of molybdenite mistaken for galena . Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal. 1778 , Swedish scientist Carl William Scherer (Carl Wilhelm Scheele) molybdenite with nitric acid decomposition obtained when molybdic acid , and obtained molybdenum salt , the same year made ​​out of molybdenum , confirming the presence of molybdenum plating , and the Greeks borrowed misunderstanding will be named molybdos. Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal. 1782 , Scherrer compatriot Peter Jacob Hjelm (Peter Jacob Hjelm) tune with linseed oil mixture over molybdate confined burning charcoal and successfully restore this oxide to obtain a ferrous metal powder , metal powder and said this is " Mo ", molybdenum. Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal. In 1893, the German chemist M. Moissan electric furnace heating a mixture of carbon and two molybdenum oxide , molybdenum content obtained in 92% to 96 % of the cast metal molybdenum . Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal. Early 20th century , do not尔齐利乌斯reduction with hydrogen trioxide has been more pure molybdenum . Copper Lead Zinc Tin CNMN.COM.CN nickel , China Nonferrous network, a small metal , scrap metal.
