Molybdenum is a silver-white metal, hard and tough. All kinds of
tissues in human body contain molybdenum, the total amount in human
body is about 9 mg, and the highest content is in liver and
kidney. Molybdenum is a silver-white metal with an atomic radius of
0.14 nm, atomic volume of 235.5px/mol and coordination number
of 8. The crystal is an AZ-type body centered cubic crystal system
with space group Oh9. So far, no isomerism transformation has been
found in it. Molybdenum, which has a high melting point, is the
sixth most common element in nature and is called a refractory
metal. Molybdenum is mainly used in the iron and steel industry,
most of which are directly used in steelmaking or cast iron after
pressing industrial molybdenum oxide, and a small part is melted
into ferric molybdenum and then used in steelmaking. The content of
molybdenum in low alloy steel is not more than 1%, but the
consumption of this aspect accounts for about 50% of the total
consumption of molybdenum. The addition of molybdenum to stainless
steel can improve the corrosion resistance of steel. Adding
molybdenum to cast iron can improve its strength and wear
resistance. Nickel-based super alloy containing 18% molybdenum has
the characteristics of high melting point, low density and small
thermal expansion coefficient, etc., which is used in the
manufacture of various high temperature resistant parts in aviation
and aerospace. Molybdenum metal is widely used in electronic
devices such as electron tubes, transistors and rectifiers.
Molybdenum oxide and molybdate are excellent catalysts in the
chemical and petroleum industries. Molybdenum disulfide is an
important lubricant used in the aerospace and mechanical
industries. In addition, due to its unique anti-sulfur properties,
molybdenum disulfide can catalyze the hydrogenation of carbon
monoxide to alcohols under certain conditions, and is a very
promising CHEMICAL catalyst for C1. Molybdenum is one of the
essential trace elements in plants and is used as trace element
fertilizer in agriculture.
