The characteristics and application of molybdenum
The density of molybdenum is 10.2 g / cubic centimeter, the melting point is 2610℃, and the boiling point is 5560℃. Molybdenum is a kind of transitional element, which is easy to change its oxidation state. The stable value is +6.
Molybdenum is mainly used for the steel industry, the most of molybdenum is used for steelmaking or ironmaking directly in the form of oxide molybdenum block and the less of molybdenum is used for steelmaking after melting into ferromolybdenum. The content of molybdenum in low alloy steel is not more than 1%, but the consumption accounts for about 50% of total molybdenum. Adding the molybdenum into stainless steel can improve the corrosion resistance of steel. And adding molybdenum into casting iron can improve the strength and wear resistance of iron. Nickel alloy with 18% molybdenum has the characteristics of high melting point, low density and low thermal expansion coefficient, which is used for various high temperature components of the aviation and aerospace manufacturing. Metal molybdenum is also widely used in electronic devices such as electronic tubes, transistors and rectifiers.
Molybdenum products are widely used in industry. Pure molybdenum wire is used in the processing of high temperature electric furnace and electric spark and also used in the wire cutting process. Molybdenum sheet is used in the manufacture of radio equipment and X-ray equipment. Molybdenum crucible is used in the refining of rare earth. Molybdenum and molybdenum alloy have resistant high temperature ablation, which is mainly used for the manufacturing of heat flow, artillery gun, rocket nozzle and the tungsten wire ‘s support of electric light bulb.
