Rare earth oxides from rare earth extract oxide, erbium oxide, main; lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide, eur oxide dysprosium oxide, etc..
Rare earth oxides refers to the periodic table of elements atomic number is 57 to 71 of the 15 lanthanide oxide, as well as with lanthanide chemistry properties similar to those of scandium yttrium ( Sc ) and ( Y ) a total of 17 kinds of oxides of the elements. Rare earth elements in petroleum, chemical, metallurgical, textile, ceramic, glass, permanent magnetic materials and other fields have been widely used, with the progress of science and technology breakthroughs, rare earth oxide value will be more and more big.
