Molybdenum is one of the rare alloying elements that, when introduced in small amounts into an alloy, significantly increases strength and resistance to corrosion. This element is quite ductile. But when alloying - with increasing strength, molybdenum increases the brittleness of alloys. It has been used since ancient Japan to produce edged weapons. Modern metallurgy uses molybdenum as a base for alloying heat-resistant and corrosion-resistant alloys. Wires and bands of this material are used for heating elements of high-temperature furnaces, ways of current lead in a light bulb. Molybdenum compounds of all kinds: sulfides, oxides, molybdates are used as catalysts of reactions and coloring pigments. Molybdenum hexafluoride is used when applying metallic Mo to various materials, _MoS2 is used as a solid high-temperature lubricant, and molybdenum disilicide is used in heaters with oxidizing atmospheres.

Production .

Molybdenum is rarely found in native form, sometimes as part of meteorites. The percentage of this metal in the Earth's crust does not exceed 4%. Molybdenum ore is generally very poor, making it difficult to mine for processing. The technology of enrichment and production of the metal must be strictly observed at each stage, as otherwise the product can contain a large amount of impurities. During oxidation, molybdenum significantly loses its strength.

Advantages of molybdenum

Heat resistance, very high elasticity index, minimal thermal expansion coefficient, small thermal neutron capture cross-section. Electrical conductivity of molybdenum is lower than that of copper, but better than that of iron. It is slightly inferior to tungsten in terms of strength data, but it is easier to operate and pressure treat. In addition, molybdenum, as mentioned above, is quite strong and extremely refractory, which allows it to improve the performance of the alloys in which it is present.

Use

Molybdenum is a valuable component in alloys for the automotive, aviation and space industries. Despite the small percentage of molybdenum production, its use by the steel industry is increasing rapidly every year. Most of the molybdenum produced is used as alloying agent for iron or steel alloys. Molybdenum compounds have found application in glassmaking and ceramics production.
