Introduction of molybdenum

 Molybdenum is a metallic gray metal which was discovered in 1778. Its atomic number is 42 and atomic mass is equal to 95.94.

Its concentrate or sulfur is obtained as MoO3 after necessary processes.

This product (MoO3) is used as basic material of Molybdenum derivations in iron melting, alloy steels and castings industries.

Molybdenum is agent of rigidity, strength and also it enhances the properties and temperature of the alloys.

Main consumption of Molybdenum in alloys

90% of Molybdenum is applied to produce the high resistant alloys and special steels and the industries such as: Stainless alloys, special alloys, aerial and spatial industries. Molybdenum is compared with the iron super alloys, Nickel, Cobalt, and other refractory metals like: Tungsten, Tantalum and Niobium. It is mentionable that super alloys can be used in temperatures to 1200°c

Main consumption of Molybdenum in glasswork

 Molybdenum is resistant to corrosion by most glasses, thus it is applied as electrode material in glass melting furnaces. The glasses which are produced in these furnaces are higher quality than glasses produced in fuel furnaces and also process of glass production using molybdenum is environmentally more accepted.

Main consumption of Molybdenum in electronic

Molybdenum is used in electronic applications specially in conducting the metallic layers inside thin film transistors. Its high thermal resistance and low thermal expansion coefficient is very important in this type of application.

Molybdenum discs in the base plates and thermal sinks are applied to power transmit and silica rectifiers.

Chemical consumption

Molybdenum is used as dyes from red-yellow to orange, light red in color production, inks, plastics and rubber industries. Molybdenum disulfate is a good lubricant (oil) or grease in high temperatures.


 Molybdenum is used as catalyst in petroleum industry especially in the catalysts to separate the organic sulfurs from petroleum products.
