Molybdenum is a chemical element with the symbol Mo and atomic number 94. It is a yellow-green hard metal with good wear resistance, corrosion resistance and high melting point. Molybdenum has a wide range of applications, including in the chemical industry, metallurgy, electronics, medicine and other fields. Molybdenum is mainly used in the form of molybdenum disulfide, molybdenum oxide, molybdenum silicide and other compounds. In addition to being a kind of rare and valuable raw material for various high-tech industries, molybdenum is also widely used in traditional industries such as coal and iron ore mining, in order to improve production efficiency and improve production safety.
The physical features of molybdenum include high density, hardness, ductility and malleability. It can be welded and processed by ordinary welding methods. Molybdenum has a good corrosion resistance to acids, alkalis and some organic substances. It is resistant to high temperatures and atmospheric corrosion, and has good electrical properties and heat conductivity.
Molybdenum applications are extensive, including in the chemical industry, petroleum refining, power generation, steelmaking, construction, medicine and other fields. Molybdenum can be used as a catalyst or intermediate in the production of sulfuric acid, nylon, glass fiber, etc. It can also be used as a material for welding and welding rods in the field of construction and other industries. Molybdenum alloys can also be used in aerospace engineering, nuclear power generation and other fields.
