The distribution and geological exploration of molybdenum in China
In the metallurgical industry, molybdenum is used as an additive in the production of various alloy steels, or as a senior alloy with tungsten, nickel, cobalt, zirconium, titanium, vanadium, rhenium, etc., to improve its high temperature strength, wear resistance and corrosion resistance.Molybdenum-containing alloy steel is used to make transportation devices, locomotives, industrial machinery, and various instruments.Certain stainless steels containing 4 ~ 5% molybdenum are used for the production of precision chemical instruments and equipment used in seawater environments.High speed cutting tools can be made from 4% ~ 9.5% high speed steel.Alloys of molybdenum, nickel and chromium are used in the manufacture of metal components for aircraft, and corrosion resistant parts for locomotives and automobiles.Alloys of molybdenum and tungsten, chromium and vanadium are used in the manufacture of alloy components and parts for warships, tanks, guns, rockets and satellites.
Molybdenum is widely used as heating material and structural material of high temperature electric furnace, large electrode and gate of vacuum tube, semiconductor and electric light source material.Molybdenum can also be used as structural material for nuclear reactors because of its small thermal neutron capture cross section and high endurance strength.
In the chemical industry, molybdenum is mainly used in lubricants, catalysts and pigments.Molybdenum disulfide is widely used as an additive for oil and grease because of its laminated crystal structure and surface chemical properties and good lubricating properties at high temperature and pressure.Molybdenum is a catalyst component in hydrogen desulfurization and other petroleum refining processes.Molybdenum orange is an important pigment.Molybdenum chemicals are widely used in dyes, inks, color precipitated dyes, antiseptic primers.
