What Are The Uses Of Molybdenum Metal?

Molybdenum is mainly used in the iron and steel industry, where it is mostly briquetted as industrial molybdenum oxide and used directly in steelmaking or iron casting, and to a lesser extent melted down into ferromolybdenum and molybdenum foils before being used in steelmaking. The molybdenum content in low alloy steel is not more than 1%, but the consumption in this area accounts for about 50% of the total molybdenum consumption. The addition of molybdenum to stainless steel improves the corrosion resistance of the steel. The addition of molybdenum to cast iron improves its strength and wear resistance. Nickel-based superalloys containing 18% molybdenum have high melting points, low densities and small coefficients of thermal expansion, etc., and are used in the manufacture of a variety of high-temperature components for aviation and aerospace. Molybdenum metal is widely used in electronic devices such as 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, molybdenum disulfide can catalyze the hydrogenation of carbon monoxide to alcohols under certain conditions due to its unique sulfur-resistant properties, making it a promising catalyst for C1 chemistry. Molybdenum is one of the essential trace elements for plants and is used as a trace element fertilizer in agriculture. Pure molybdenum wire is used in high-temperature furnaces and electric spark processing and wire-cutting; molybdenum sheet is used in the manufacture of radio equipment and X-ray equipment; molybdenum is resistant to high-temperature molybdenum crucible ablation, mainly used in artillery chambers, rocket nozzles, the manufacture of tungsten filament brackets for electric light bulbs. Alloy steel with molybdenum can improve the elastic limit, corrosion resistance and maintain permanent magnetism, etc., molybdenum is a plant growth and development of the seven micronutrients needed in one, without it, plants can not survive. Animals and fish need molybdenum just as much as plants. Molybdenum is also used in other alloys and in the chemical industry in an ever-expanding range of applications. For example, molybdenum disulphide lubricants are widely used in the lubrication of various types of machinery, and molybdenum metal is gradually being used in the fields of nuclear power and new energy. Because of the importance of molybdenum, governments regard it as a strategic metal, molybdenum in the early twentieth century was used in large quantities in the manufacture of weapons and equipment, modern high-precision, sophisticated equipment on the material requirements of higher, such as molybdenum and tungsten, chromium, vanadium alloys used in the manufacture of warships, rockets, satellites, alloy components and parts. Molybdenum in the thin film solar energy and other coating industry, as a substrate for different film surface is also widely used.
