Introduction to rare earth elements and nanomaterials
- Mar 16, 2018 -

Characteristics of rare earth elements: rare earth elements have special atomic structure, and the inner 4f orbital has no pair of electrons and high atomic magnetic moment. The electron energy level is extremely rich, which is one to three orders of magnitude more than all the other elements in the periodic table. Rare earth metals and lively, almost with all elements, easy to lose electrons to form a variety of valence and coordination number (from 3 to 12) compounds, so rare earth is considered to be the new light source, a new magnetic source, new energy, new materials of treasure, is also the touchstone of transforming traditional materials industry.
