How are rare earth metals extracted
WebThe rare-earth metals readily react with hydrogen to form RH2, and, by raising the hydrogen pressure, the trivalent R metals (except for scandium) also form the RH3 phase. Both the RH2 and RH3 phases are nonstoichiometric (that is, the numbers of atoms of the elements present cannot be expressed as a ratio of small whole numbers).
