Lutetium is a metal that is within the rare earth group, this being the most difficult to obtain or isolate compared to the other members of the lanthanides, it has an atomic number of 71 and its molecular weight corresponds to 174.9 In the same way, it is the counterpart with the other lanthanide elements, it is the heaviest and has a higher hardness index, it has a silver color with small whitish tones, it is stable in the presence of oxygen and can expose radioactivity.

The first scientists who identified lutetium respond to the name of George Urbain and Carl Auer von Welcbach, from France and Australia, respectively, an event that occurred in 1907, the origin of the name Lutetium is Greek “Lutetia” which means Paris, because the pure extraction occurred in that city.

The most practical and simple way within the dimensions of the word, to obtain lutetium is through the reduction of lutetium triochloride or triofluoride, this is achieved by working with anhydrides of an alkali metal or alternatively alkaline earth metal. Lutetium, ythyrium and lanthanum have prominence in the area of ​​science as strongly magnetic metals, the main reason why they are highly sought after by scientists, this property is thanks to the fact that they form trivalent ions which generates the presence of unpaired electrons , which significantly increases the ferromagnetic power of its salts, lutetium is considered to be the most expensive metal of the lanthanide group and this is caused by the difficulty in obtaining it, despite this lutetium is It is free on the market, therefore it is not necessary to prepare it in the work laboratory.

This chemical element is widely used in refineries, since it is used as a catalyst (accelerator) of reactions such as oil cracking, it can also be used in other interactions that can be mentioned are alkalinization, polymerization and hydrogenation; In turn, recent analyzes have been carried out to evaluate the role of lutetium as a therapeutic treatment at the level of nuclear medicine.
