Purification of the Rare Earth Metals SpringerLink

Abstract. The rare earth elements have a history of intriguing scientists with their rich variety of physical properties. Early attempts to investigate these properties were hampered, however, by a lack of suitably pure sampies, for it so on came to be realized that the intrinsic properties of these notoriously reactive metals could only be measured if their typical impurity levels were ...
