Introduction to the knowledge of ytterbium oxide and erbium oxide
Ytterbium oxide, also called ytterbium trioxide, has the chemical formula Yb2O3. The pure product is a white powder, and it is yellowish-brown when it contains a small amount of thorium oxide. Insoluble in water and cold acid, soluble in warm dilute acid.
Erbium oxide is a pink powder with the chemical formula Er2O3. It easily absorbs moisture and carbon dioxide, and becomes a hexagonal crystal when heated to 1300 ℃, and does not melt. Then is synthesized from lanthanum metal. In 1843, it was partially isolated by Carl Gustaf Mosander. In 1905, Georges Urbain and Charles James proved for the first time that it has a pure pink cubic crystal structure. Oxidation can also be hexagonal under certain conditions.
How to prepare ytterbium oxide and erbium oxide
Preparation method of ytterbium oxide
Taking brown yttrium niobium ore as raw material, through multi-step separation to obtain rich thulium and ytterbium aqueous solution, oxalic acid precipitation separation, filtration, and burning to prepare ytterbium oxide.
Preparation method of erbium oxide
After separation and burning, erbium oxide is obtained by reacting nitric acid or sulfuric acid solution with alkali.

Uses of ytterbium oxide and erbium oxide
Ytterbium Oxide: Mainly used in the manufacture of computer magnetic bubble materials, so that magnetic bubble storage has the characteristics of high speed, small size, large capacity, and multi-function.
Erbium oxide: Erbium oxide is mainly used as an additive for yttrium iron garnet and as a control material for nuclear reactors. It is also used to make special light-emitting glass and infrared absorption glass. It is also used as a glass colorant. The only stable compound is Er2O3. Oxidation is a powdery substance with a cubic and monoclinic structure centered on the body. The magnetic moment of Er2O3 is also larger, 9.5MB. Other properties and preparation methods of oxidation properties are the same as those of lanthanides. Oxidation can be made into pink glass.

How to store powder
A humid environment will affect the dispersion performance and use the effect of the powder. Therefore, it should be sealed in a vacuum package and stored in a cool and dry room. It should not be exposed to the air. In addition, avoid using powder under pressure.
