Introduction

The Most Expensive of All Rare Earth Elements

Lutetium is the most expensive rare earth element and plays a role primarily in highly specialized applications.

Three Independent Researchers, One New Element

Lutetium was discovered independently in 1907 by Georges Urbain in France, Charles James in the US, and the Austrian chemist Carl Auer von Welsbach. In 1909, Urbain was officially recognized as the discoverer by the International Atomic Weights and Measures Committee. He proposed naming it Lutecium, the Latin name of his native city of Paris. In 1949, the spelling was changed to Lutetium, the name used today. In German-speaking countries in particular, the element was long known as Cassiopeium, the name proposed by von Welsbach.

The Discoverer of Lutetium

The French chemist Georges Urbain was born in Paris in 1872. A specialist in rare earths, he received numerous awards for his research and was a member and president of renowned institutes. He was also interested in art and was a painter, composer, and sculptor.

Characteristics

Highest Density and Melting Temperature of All Lanthanides

Lutetium is a shiny, silvery metal. Of all the lanthanides, it has the highest density and the highest melting temperature.

Areas of Application

Highly Specialized Applications

Lutetium is the most expensive rare earth, as it is difficult to separate from the other representatives of this group of raw materials. It is a highly specialized metal that has only a few applications, which explains its high price. Lutetium is used to manufacture computer chips using the immersion lithography processA process used in the manufacture of microelectronics, such as chips., as a catalyst for refining crude oil, and in infrared lasers. Lutetium also has some applications in medicine.

Catalysts

Catalysts increase the speed of a chemical reaction and are indispensable in many industries. In automotive catalytic converters, for example, catalysts convert combustion pollutants into non-toxic residues.

Lutetium: Relaxed Supply in the Medium Term

Like the other heavy rare earths, lutetium is mainly derived from ion adsorption clays, which occur in only a few regions with strong weathering, such as southern China and Myanmar. Rare earths are extracted from the clays by leaching. In subsequent processes, the elements are selectively separated using organic solvents. After thulium and the unstable promethium, lutetium is the rarest lanthanide.

The map shows the regions of the world where heavy rare earths are currently mined.

High Price Despite a Relaxed Supply Situation

As the number of fields of application for lutetium is comparatively low, the supply situation is considered to be relaxed in the medium term. Nevertheless, the price of lutetium is correspondingly high due to its complex separation process. The high regional concentration of mining and processing poses a risk.

  • China has market power over heavy rare earths such as lutetium
  • Heavy rare earths are often illegally mined
