WONDROUS REAR EARTH WORLD

RE oxide series:

Based on our advanced solvent extraction and separation techniques, the whole spectrum of rare earth oxides, such as yttrium oxide, yttrium-europium oxide, europium oxide, lanthanum oxide, terbium oxide (including cerium-terbium oxide, lanthanum-cerium-terbium oxide), samarium oxide, neodymium oxide, dysprosium oxide, erbium oxide, ytterbium oxide, as well as cerium-zirconium oxide, that being used as a catalytic converter for auto's exhaust gases, has been produced in our company under the on-line monitoring and control system.

RE metals and their alloys:

A whole family of RE metals and their alloys, such as samarium, yttrium, dysprosium, lanthanum-rich misch metal and flints, that are being used as additives for permanent magnetic materials, hydrogen storage materials and various alloys.

The RE oxides produced and their applicable areas are listed in as follows:
