Introduction to ytterbium dioxide and erbium Oxide Ytterbium oxide It is also called ytterbium dioxide and has the chemical formula: Yb2O3. It is a white powder when pure, and yellowish brown if it contains some thorium oxid. Insoluble in cold acid and water, but soluble in warm dilute acetate.
Erbium oxide The chemical formula of Er2O3 is pink powder. It is a pink powder with the chemical formula Er2O3. When heated up to 1300, it turns into a hexagonal, non-melting crystal. It is first synthesized using lanthanum. Carl Gustaf Mosander isolated it partially in 1843. Georges Urbain & Charles James demonstrated for the first in 1905 its pure pink cubic structure. Oxidation may also take a hexagonal shape under certain circumstances.
How to prepare Erbium oxide and ytterbium dioxide
The preparation method of ytterbium oxid
The resulting ytterbium is obtained by separating oxalic acids, filtering, burning, and separating thulium from ytterbium-rich aqueous solutions.
Method of preparation of erbium dioxide
After separation and burn, erbium dioxide is obtained from nitric or sulfuric acid solutions by reacting them with alkali.

Uses for ytterbium Oxide and Erbium Oxide
Ytterbium-oxide: This oxide is mainly used in the production of magnetic bubble materials for computers. Magnetic bubble storages have the following characteristics: high speed, compact size, large volume, and multiple functions.
Erbiumoxide: Erbiumoxide is mainly used in yttrium ferro garnet as an additif and also as a control for nuclear reactors. Also, it is used in the production of special light-emitting and infrared absorbent glasses. It is used to color glass. Er2O3 remains the only stable substance. Oxidation occurs as a powdery substance that has a cubical and monoclinic shape centered in the body. Er2O3 also has a greater magnetic moment (9.5MB). These properties, as well as the preparation methods for oxidation, are identical to those of lanthanides. The pink color of glass can be achieved by oxidation.

How to store powder
A humid environment can affect the powder’s dispersion and its use. The powder should be kept in a sealed vacuum package in a cool, dry environment. The powder should not be left exposed to the atmosphere. Use powder only under pressure.
