Rare earth metals:
What they are, what they apply and why we request them
Rare earth elements are essential natural materials for many key technologies, from electronic products to medical equipment.
What are uncommon earth metals?
Rare earth metals are a group of 17 chemical elements including scandium, yttrium and lanthanums, ranging from lanthanum (La) to lutetium (Lu).
In practice uncommon earth metals are essential in modern technologies due to their unique magnetic, luminescent and catalytic properties. They are crucial for the production of electronics, advanced materials and medical and energy technologies.
The names of uncommon earths have different origins – from mythology to scholarly names and places.
Samar (Sm, atomic number 62) – named after Wasyl Samarski, a Russian engineer moving the mine, in which a mineral containing this component was discovered. Samar is utilized in magnets, lasers and electron capture devices.
Neodym (Nd, atomic number 60) – the name is derived from Greek neos (new) and didymos (twin). Neodym is simply a key component of supermagnets utilized in automotive and electronic industries.
Metals specified as neodymium, gadoline and dysprosium are crucial in the production of smartphones, laptops, speakers, hard drives, plasma screens and another electronic devices. For example, neodymium magnets are utilized in electrical motors and hard drives, where their advanced magnetic power is invaluable.
Neodym and samar are utilized to manufacture electrical and hybrid engines. Wind turbines besides contain uncommon earth metals, which is crucial for the production of renewable energy.
