Molybdenum is used mainly in special steel alloys, where it provides important improvements such as: greater hardness, resistance to high temperatures and corrosion, increased durability and greater efficiency of machinery. There are also uses of Molybdenum in fertilizers, catalysts, lubricants, among other products. Molybdenum is presented in different formats, the most frequent being the technical molybdenum oxide, ferromolybdenum, ammonium dimolybdate, pure oxide and metallic molybdenum.

Although products from the 14th century have been found with applications of Molybdenum, their use only became common in the late 19th century. By then, the first experiments showed that molybdenum could replace tungsten in many steel alloys, achieving lower weight and greater strength. Subsequently, World War I increased the demand for steel, restricting the supply of tungsten. This shortage was an impetus for the use of Molybdenum and for the research of new applications of this mineral which has proven to be an invaluable component for nickel-based superalloys, lubricants, chemicals, electronics and many other applications.

Molybdenum is a natural element that, in addition to being a mineral, is found in low concentrations in plants, animals and even within the human body. Therefore, Molybdenum is essential for life.
