White Powder 99.9% Yttrium Oxide O3Yb2 CAS No 1314-37-0

White powder, yellowish brown when containing a small amount of thorium oxide. Insoluble in water and cold acid, soluble in warm dilute acid.

Mainly used in the manufacture of magnetic bubble materials for computers, so that the magnetic bubble storage has the characteristics of high speed, large capacity, small volume, and multi-function.

Used in the manufacture of special alloys, dielectric ceramics and special glasses.

Used in phosphors, optical glass additives and electronics industry

The mixed rare earth obtained by decomposing brown yttrium niobium ore contains Y2O350% and CeO2 about 4%. The rare earth nitrate solution after removing the cerium is fed with N263-LiNO. The system is extracted and grouped to obtain the yttrium-rich rare earth. N263-heavy solvent-NH4SCN system extracts and purifies yttrium, the raffinate is yttrium-rich rare earth, thulium, ytterbium, and lutetium heavy rare earths enter the organic phase, and then the thulium and lutetium are grouped by N263-heavy solvent extraction, and thulium and ytterbium are back-extracted with hydrochloric acid Into the water phase, oxalic acid precipitation and separation, filtration, and burning, to prepare ytterbium oxide.
