The introduction to the knowledge and application of erbium or ytterbium oxid
Also known as ytterbium dioxide, the chemical formula is Yb2O3. It is a pure white powder. When it contains small amounts of thorium dioxide, it becomes yellowish brown. Water and cold acids are insoluble. Warm dilute acid is soluble.
Erbiumoxid is pink powder with chemical formula Er2O3. When heated to 1300°C, it absorbs water and carbon dioxide easily. However, it does not melt. This is how lanthanum-metal metal can be synthesized. Carl Gustaf Mosander was able to partially isolate it in 1843. Charles James and Georges Urbain demonstrated for the first times in 1905 that this crystal has a clear pink cubic structure. In certain situations, hexagonal oxygen can be achieved.
Making erbium or ytterbium oxalate
The preparation method for ytterbium oxid
Multi-step separation of brown yttrium oxide ore to extract rich thulium/ytterbium. Oxalic acid precipitation separation separation, filtration and burning are all used to produce ytterbiumoxide.
The preparation method for erbium oxide
Following separation and burning, the erbium-oxygen reaction with nitric acid/sulfuric acid solution in an alkali reacts to produce erbiumoxid.
Uses for ytterbium oxide and erbium ole
Ytterbium Oxide: This substance is used mainly in the production of computer magnetic materials. Thus, magnetic bubble storage exhibits the characteristics of large size, speed and multiple-function.
Erbium Oxide: Erbiumoxid can be used as an ingredient in ytrium-iron garnet or as a control material to nuclear reactors. This is used for making special light emitting and infrared absorb glass. This compound can be used to color glass. Er2O3 remains the most stable compound. The stable compound Er2O3 is the only one. The magnet moment of Er2O3 also is higher, at 9.5MB. There are many other properties, as well as methods for preparing oxidation property properties. These properties are identical to those of Lanthanides. You can make pink glass by using oxidation.
How to store the powder
The powder’s dispersion performance will be affected by humidity. The powder should be stored dry in cool, dry places and kept in a sealed vacuum container. It shouldn’t be in direct contact with the atmosphere. Also, powder should never be pressured.
