Neodymium grades, chemical composition
General Characteristics
Neodymium is a rare earth element of the lanthanoid group. The chemical symbol is Nd. It is a white-silver metal with a yellowish tint. It is easily oxidized in the air. It was discovered in 1885. Austrian chemist Karl Auer von Welsbach was able to separate the rare-earth metal didim, previously thought to be a single element, into praseodymium and neodymium. The word neodymium means "new twin" in Greek. This metal is industrially produced by calcithermal reduction or electrolysis of anhydrous praseodymium and neodymium halides. The main suppliers of this metal to Europe are: China, USA, Ukraine, Kazakhstan and Scandinavian countries.

Applications
It is one of the most sought after lanthanides for the manufacture of powerful permanent magnets and infrared lasers with a wavelength of about 1.067 µm. It is required for melting colored violet glass. NdF3 fluoride is used in fiber optics to produce high quality glass fibers. Nd2 O3 oxide, a dielectric, has a minimal coefficient of expansion. This metal greatly strengthens thermoelectric materials based on tellurides, antimony selenides and bismuth, and increases their thermo-EDC. It has been worked out that neodymium doping of bismuth-tellurium-zesium-based materials also has a beneficial effect on their properties. Neodymium is used in agriculture. Seeds treated with it have better germination and yield. This metal is indispensable for alloying of structural steels and alloys. It makes pure titanium stronger by 1.5 times. Upon chemical interaction with aluminum, compounds are formed that double the alloy's tensile strength and several times its hardness. Aluminum-Neodymium-Titanium alloys are used to produce rolled products such as rounds, wires, sheets and strips,
