Molybdenum in the chemical industry

Molybdenum grease lubricant: Molybdenum dioxide is a good solid lubricant because of its low coefficient of friction, high yield strength, and its ability to function properly in vacuum and at various ultra-low and high temperatures, and is therefore widely used in gas turbines, gears, molds, aerospace, nuclear industry and other fields.
Catalyst: Molybdenum compounds are one of the most versatile catalysts and are widely used in the chemical, petroleum, plastics, textile and other industries. For example: molybdenum disulfide has anti-sulfur properties, and can catalyze the hydrogenation of carbon monoxide to produce alcohols under certain conditions, which is a promising C1 chemical catalyst; molybdenum is used in combination with cobalt and nickel as a catalyst for petroleum refining pretreatment. Other common catalysts containing molybdenum are: molybdenum disulfide, molybdenum oxide, molybdate, ammonium sec-molybdate and so on.

Pigment: Chrome yellow and cadmium yellow are the most commonly used inorganic yellow pigments in the world today, but lead, chromium and cadmium are toxic, while molybdenum yellow is not only non-toxic, but also has a bright color, light and heat stability is also good, and thus is used in pigments and inks, plastics, rubber products and ceramics.
Organic polymer flame retardant and smoke reducer: in halogenated polyester by adding 3% -4% of molybdenum trioxide, the critical oxygen index can be increased by 3% -4%, the amount of carbon generated during combustion increased by 4% or so, so that the amount of smoke reduced by 3%.
Corrosion Inhibitor: Molybdate has very low toxicity and weak corrosiveness to organic additives added in corrosion inhibitors, commonly used in the construction of air conditioning cooling water and heating systems to prevent mild steel from being corroded.
