[0002] Rare earth is a collective name for 17 chemical elements in the III group of the periodic table, including scandium, yttrium and lanthanide elements. They generally exist in the form of oxides and are non-renewable resources. Rare earth is not rare, but the process of turning it into a useful material is complicated, cumbersome and costly, hence the name "rare earth". Before use, it needs to be separated from the solid and liquid, and then a filter press is used.
