Where can I buy rare earth metals
RARE EARTH METALS
In the following, all 16 natural rare earth metals are briefly presented and their basic properties and the most important areas of application are explained.
Rare earth metals, also known as "rare earths" or "rare earth metals", are a group of elements that are enjoying a rapidly increasing popularity. These are the so-called "lanthanoids", which can be found in the 3rd subgroup in the periodic table of elements, as well as the elements scandium and yttrium.
The already frightening dynamism with which these metals force their way into our everyday life is the result of a dramatic restriction on export quotas by China, which is the main producing country with approx. 95% of the share of world production.

After europium, cerium is the second most reactive metal of the lanthanoids. Due to its unique properties, it is used in catalysts, UV filters and modern picture tubes.
Dysprosium is of enormous importance in modern industry: It is used in nuclear applications, energy-saving lamps, for laser materials and in permanent magnets. Especially for permanent magnets, the demand for dysprosium will increase sharply in the future, as power generators and electric cars are dependent on this element.
Erbium is used in optical fibers to amplify optical signals. Heat meters and medical lasers also rely on erbium.
Europium is mainly used in color picture tubes and in semiconductor technology. The addition of small amounts of europium changes the properties of raw materials.
Gadolinium is used in microwave and radar technology. Gadolinium also plays an important role in medical technology and in nuclear reactors.
Due to its excellent magnetic properties, holmium has many special areas of application, such as the generation of strong magnetic fields.
Lanthanum is mainly used as an alloy metal. Areas of application are cathodes, PTC thermistors, fuel cells, accumulators, medical devices and optical applications.
Lutetium is mainly used in nuclear medicine, in computer tomographs.
Neodymium is important for the production of strong magnets, magnetic resonance imaging scanners, generators, electric cars, lasers and loudspeakers.
Praseodymium is mainly used in alloys to give the base metals special properties.
Samarium is used in medical technology, in lasers and as a magnetic material as well as for the absorption of infrared light and as a catalyst.
Scandium gives alloys special properties and makes them very stable despite their low weight. Scandium alloys are therefore often used for load-bearing elements in aircraft construction, among other things.
Terbium is used in the semiconductor industry, in fuel cells, modern light sources, lasers, magnetic storage media, permanent magnets and motors for electric cars.
Thulium activates phosphors, is used in X-ray machines and is required in lasers.
Ytterbium is mainly used as an alloy additive for stainless steel and is used to a limited extent in high-power lasers.
Yttrium is used in reactor technology, metallurgy, laser technology, fuel cells, microwave technology, picture tubes, fluorescent tubes, modern displays and in modern parts of automotive technology.
