Rare earth elements are a set of seventeen metallic elements. These elements include the fifteen lanthanides on the periodic table plus scandium and yttrium. These elements are considered "rare" not because they are necessarily scarce, but because they are dispersed and not often found in concentrated deposits. They do not use large volumes or large amounts of base metals, such as iron and aluminum, and are mostly used for more professional purposes, so their names and properties are not well known in daily life. It has an irreplaceable role in industrial production. Automobile glass, nuclear magnetic resonance, optical fiber, liquid crystal display screen and so on are inseparable from the addition of rare earth.
