Molybdenum applications in the chemical industry are: lubricants, catalysts, pigments, flame retardants and organic polymers smoke suppressants and corrosion inhibitors and other aspects.
In terms of lubricant, molybdenum dioxide as molybdenum oxide is a good solid lubricant, its low friction coefficient, high yield strength, can be used normally under vacuum and a variety of ultra-low temperature, high temperature, which is widely applied to gas turbines, gears, molds, aerospace, nuclear industry and other fields.
The molybdenum compounds used in the catalyst is very broad terms, including chemical, petroleum plastics, textiles and other industries. Other common molybdenum catalysts containing: molybdenum disulfide, molybdenum oxide, molybdate, ammonium paramolybdate and so on.
Molybdenum yellow used as inorganic yellow pigments, compare with chrome yellow and cadmium yellow it is not only non-toxic, but also has a bright color, light, heat stability good, they have been used in paints and inks, plastics, rubber products and ceramics .
While molybdenum application in flame retardants and smoke suppressants by adding 3-4% molybdenum trioxide into halogenated polyester and make critical oxygen index increased by 3% -4%, When burning the amount of carbon increasing generated about 4%, reduction in the amount of smoke so.
