Classified by extraction separation: rare earth elements in the periodic table of the rare earth elements in the periodic table location light rare earth (
P204 weak acidity extraction)
Lanthanum, cerium, praseodymium, neodymium;
In the rare earth (
P204 low acidity extraction)
Samarium, europium, gadolinium, terbium and dysprosium;
Heavy rare earth (
Acidity in P204 extraction)
Holmium and erbium, thulium, ytterbium and lutetium, yttrium.
Commonly referred to in the natural strong magnet ferrite (not just the
Iron, cobalt, nickel and iron alloy, rare earth alloy, etc. All kinds of permanent magnetic materials, such as aluminum nickel and cobalt, samarium cobalt, ndfeb, these are also common, magnetic is very strong, these substances can be magnetization of the magnetic field of constant magnetic field, and after magnetization itself has a magnetic and don't disappear.
The magnet close (
Induction of magnetic materials, the material near the end into the unlike poles, while the other end to generate the same name.
