Molybdenum, like tungsten, is a refractory rare metal. The application of molybdenum in the iron and steel industry occupies a very important position, accounting for about 80% of the total consumption of molybdenum, followed by the chemical industry, accounting for about 10%. In addition, molybdenum is also used in fields such as electrical and electronic technology, medicine and agriculture, accounting for about 10% of the total consumption.

The consumption of molybdenum in the field of steel is large, mainly for the production of alloy steel (accounting for about 43% of the total consumption of molybdenum in steel), stainless steel (about 23%), tool steel and high-speed steel (about 8%), cast iron and rolls (about 6%). Most of the molybdenum is briquetted from industrial molybdenum oxide and used directly for steelmaking or cast iron, while a small part is first smelted into ferromolybdenum and then used for steelmaking.
Molybdenum Grease Lubricant: Molybdenum dioxide is a good solid lubricant, because of its low friction coefficient and high yield strength, it can be used normally in vacuum and various low and high temperatures, so it is widely used in gas turbines , gears, molds, aerospace, nuclear industry and other fields.
Molybdenum compounds are one of the most widely used catalysts and are widely used in chemical, petroleum, plastic, 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. It is a promising C1 chemical catalyst; molybdenum, cobalt and nickel are used as catalysts for petroleum refining pretreatment.
