Rare earth compounds

The term "rare earth", introduced in the late XVIII century ("lands" in the language of chemists those years called refractory, insoluble oxides), is not quite correct, because the contents of these metals in the earth's crust ranges from 60 ppm for cerium up to 0 ,5 ppm for thulium and lutetium.

In other words, almost all of them are found in the earth's crust more than silver, and four of the most common elements (yttrium, lanthanum, cerium and neodymium) - to a greater extent than lead. The only truly rare in this group is promethium (atomic number 61), which is radioactive with very short half-life, and in nature it is vanishingly small.

The value of REM is continuously growing due to their use in many modern technologies, including the manufacture of catalytic converters, filters, car exhaust, fiber optics, lasers, oxygen sensors, phosphors and superconductors.

Speaking about the structure of the global consumption of REM, it should be noted that much of this material is used as a relatively cheap hybrid compounds. Large amounts of rare earth in the form of a mixture of oxides used in the steel, glass and ceramic industries. About 25% of all recovered unseparated REM is the production of separated pure metals.
