Ferromolybdenum
From Wikipedia, the free encyclopedia
Ferromolybdenum is an important iron molybdenum alloy, with a molybdenum content of 60-70%[1] It is the main source for molybdenum alloying of HSLA steel. The molybdenum is mined and is subsequently transformed into the molybdenum(VI) oxide MoO3. This oxide is mixed with iron oxide and aluminium and is reduced in the an aluminothermic reaction to molybdenum and iron. The ferromolybdenum can be purified by electron beam melting or used as it is. For alloying with steel the ferromolybdenum is added to molten steel before casting. Among the biggest suppliers of Ferromolybdenum in Europe is the German trading house Grondmet in Düsseldorf, Germany.
