A process for producing ferromolybdenum alloys by agglomerating a finely-particulated mixture containing controlled amounts of molybdenum disulfide and an iron bearing material into a plurality of pellets and heating the pellets to an elevated temperature under a controlled vacuum for a period of time sufficient to effect a dissociation of the molybdenum disulfide and an extraction of the sulfur and other volatile constituents in the pellets and an alloying of the metallic molybdenum produced with the iron bearing material producing substantially dense sintered ferromolybdenum alloy pellets.
Molybdenum disulfide is the inorganic compound with the formula MoS2.
The compound is classified as a metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. MoS2 is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite. It is widely used as a solid lubricant because of its low friction properties and robustness.
