What are Rare Earth Elements?
Rare Earth Elements consist of a group of 17 chemically similar elements that include the 15 lanthanides, along with scandium and yttrium. These elements are not actually rare in terms of abundance; rather, they are rarely found in economically exploitable concentrations. The lanthanides range from lanthanum to lutetium, while scandium and yttrium are often grouped with them due to their similar properties and behaviors in geological formations.
The unique characteristics of REEs, such as their magnetic, luminescent, and electrochemical properties, make them invaluable in various applications. For instance, neodymium is crucial for manufacturing powerful magnets used in electric motors and wind turbines, while europium is essential for producing red phosphors in LED lights and television screens. Despite their name, these elements are integral to many technologies that define modern life.
History and Discovery of Rare Earth Elements
The journey of rare earth elements began in the late 18th century when they were first isolated from minerals. The discovery of these elements can be traced back to 1787 when Swedish chemist Johan Gadolin identified a new mineral called gadolinite, which contained a previously unknown element he named yttrium. Over the following decades, scientists like Martin Heinrich Klaproth and Jöns Jacob Berzelius contributed to the identification and isolation of additional rare earth elements.
The 19th century saw significant advancements in the understanding of REEs, particularly with the work of chemists such as Carl Gustaf Mosander, who discovered lanthanum, cerium, and didymium. The term “rare earth” was coined in the early 20th century as these elements were found to be difficult to extract and purify. The development of new extraction techniques during this period laid the groundwork for the industrial use of REEs, which would later become essential in various technological applications.
