Rare earth oxides mainly refer to lanthanum oxide (La2O3), cerium oxide (CeO2), praseodymium oxide (Pr2O3), neodymium oxide (Nd2O3), promethium oxide (Pm22O3), samarium oxide (Sm2O3), europium oxide (Eu2O3), oxide Gadolinium (Gd2O3), terbium oxide (Tb2O3), dysprosium oxide (Dy2O3), holmium oxide (Ho2O3), erbium oxide (Er2O3), thulium oxide (Tm2O3), ytterbium oxide (Yb2O3), lutetium oxide (Lu2O3), scandium oxide ( Sc2O3) and yttrium oxide (Y2O3). Rare earth elements are widely used in petroleum, chemical industry, metallurgy, textile, ceramics and glass and other fields. With the development of science and technology, the use of rare earth elements will be more extensive, showing great application prospects.
Alfa Chemistry insists on providing high quality rare earth oxides, the related products we can provide include:
The atomic structure of rare earth elements can be represented by 4fx5d16s2, x from 0→14. The valence of rare earth elements has multiple valence states and has variable valence properties, such as cerium, samarium and europium. When the rare earth metal becomes an ion, the outer side of its 4f orbital will still be surrounded by the 5s25p6 electron cloud, losing 6s2 electrons and 5d1 or 4f losing an electron. Based on the large mass of rare earth elements and the large number of electron layers, it will cause f-f electron transitions to show excellent performance in fluorescence performance.
Rare earth oxides can be used as raw materials for the synthesis of other rare earth compounds, and can be widely used in the production of phosphors, optical glass, laser components, catalysts and glass ceramics, playing an important role.
