The Finnish chemist John Gadolin first discovered rare earths. In 1794, he separated the first rare earth "element" (yttrium earth, i.e. Y2O3) from a heavy ore shaped like asphalt. Because there were few rare earth minerals discovered in the 18th century, only a small amount of water-insoluble oxides could be produced by chemical methods at that time. Historically, this oxide was habitually called "earth", hence the name rare earth. Rare earth generally exists in the form of oxides and is a non-renewable resource. Rare earth is not actually rare, but the process of turning it into a useful material is complicated, cumbersome and costly, hence the name "rare earth". When rare earth is first discovered, one of its pH values ​​is usually unqualified and needs to be tested first;
