Tungsten and Molybdenum
This article is going to talk about basic knowledge about tungsten and molybdenum.
Tungsten and molybdenum belong to refractory metal. Refractory metal refers to the metal whose melting point is more than 1650℃. In nature, molybdenum exists as MoS2, Mo-gloss and PbMo04, most of which are associated ore. While, tungsten exists as（Fe，Mn）WO4、CaWO4 and Wolframite. Molybdenum and tungsten are not well-distributed. However, China reserves much of tungsten and molybdenum. At present, China can only be called a major country which reserves tungsten and molybdenum. China is not a powerful nation which owns tungsten and molybdenum. We should create a healthy market to promote healthy development of tungsten and molybdenum industry.
There are 3 common smelting methods of tungsten and molybdenum and they are: powder metallurgy, electron-beam smelting and vacuum arc melting. Among these 3 methods, powder metallurgy is commonly used.
Tungsten and molybdenum have high melting point, excellent electrical and thermal conductivity, low vapour pressure, etc.
Tungsten and molybdenum are widely applied in spacecraft, airplane, automobiles, electronic equipment, military weapons and many other fields.
