Molybdenum is mainly used in the iron and steel industry, most of which is directly used for steelmaking or cast iron after industrial molybdenum oxide briquetting, and a small part is melted into molybdenum iron molybdenum foil
And then used for steelmaking. The molybdenum content in low alloy steel is not more than 1%, but this consumption accounts for about *0% of the total consumption of molybdenum. Molybdenum can improve the corrosion resistance of stainless steel. Adding molybdenum to cast iron can improve the strength and wear resistance of iron. Nickel base superalloys containing *8% molybdenum have the characteristics of high melting point, low density and small coefficient of thermal expansion, and are used to manufacture various high-temperature components for aviation and aerospace. Molybdenum is widely used in electronic devices such as electron tubes, transistors and rectifiers. Molybdenum oxide and molybdate are excellent catalysts in chemical and petroleum industries. Molybdenum disulfide is an important lubricant used in aerospace and machinery industries. In addition, due to its unique sulfur resistance, molybdenum disulfide can catalyze the hydrogenation of carbon monoxide to produce alcohols under certain conditions, which is a promising C1 chemical catalyst. Molybdenum is one of the essential microelements for plants and is used as microelement fertilizer in agriculture.
