Introduction to the Ytterbium Oxide and Erbium Oxide


Ytterbium oxide

It is also known by the chemical name Yb2O3. It is a white powder when pure, but turns yellowish-brown if it contains some thorium oxyde. Insoluble in cold acid and water, soluble with warm dilute acid.


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. 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 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 a multi-step separation of oxalic acids, filtration separation and burning.


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 utilized 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


The dispersion and the use of the powder are affected by humidity. The powder should be kept in a sealed vacuum package in a cool, dry environment. The powder should not be left exposed to air. Use powder only under pressure.
