Introduction to ytterbium dioxide and erbium oxid Ytterbium oxide It is also called ytterbium dioxide and has the chemical formula: Yb2O3. It is white when pure, and yellowish-brown if it contains some thorium. 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. Then, it is 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. Under certain circumstances, oxidation may also take a hexagonal form.
How to prepare Erbium oxide and ytterbium dioxide
The preparation method of ytterbium oxid
The ytterbium ore can be prepared by separating the brown yttrium and niobium ores in a multi-step process to obtain a rich thulium/ytterbium solution. This is followed by oxalic precipitation separation and filtration.
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 to make magnetic bubbles for computer storage. Magnetic bubble storage has many advantages, including high speed, compact size, large capacity and multifunction.
Erbiumoxide: Erbiumoxide is used mainly as an addition to yttrium ferr garnet as well as 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.
