Centrifugal extraction machine extraction of rare earth elements erbium
erbium for silver metal, soft, insoluble in water, soluble in acid. Erbium can be used as a reactor control materials; Also can make some activator of fluorescent material.
erbium is antiferromagnetic in low temperature, for the strong ferromagnetic when near absolute zero, and superconductors. Erbium slow oxidation by air and water at room temperature, the erbium oxide red rose. Salts and oxides show pink to red.

erbium oxide erbium category
are two body centered cubic and monoclinic junction. 。 。

erbium is antiferromagnetic in low temperature, for the strong ferromagnetic when near absolute zero, and superconductors. Erbium slow oxidation by air and water at room temperature, the erbium oxide red rose. Salts and oxides show pink to red.

erbium oxide erbium category
are two body centered cubic and monoclinic structure of powder, pink powder; Insoluble in water, soluble in acid, is a kind of stable compounds. Mainly used as additive in zhe yttrium iron garnet and nuclear reactor control material, also used in the manufacture of special light and absorb the infrared glass, also used as colorants, glass making pink glass.
poison bait
is made a stir in poison food, for luring insects, mouse, etc.
erbium nitrate
is a kind of pink granular crystal, soluble in water and alcohol, dehydration, when it is heated in the humid air, easy deliquescence. For more compounds, chemical reagents, glass and other industries.
the application areas of erbium
metal, alloy of nd-fe-b alloy additives, additives, giant magnetostrictive material single oxide compounds and amplifier, optical fiber communication laser crystals, laser glass, long persistence phosphors activator, dielectric ceramic capacitor, colored glass ceramics, etc.
erbium application in hydrometallurgy
separation method of solvent extraction is a kind of has become increasingly important, in the extraction separation of erbium, extraction with P507 hydrochloric acid system, get a load of pure erbium organic phase, and the extraction using mostly concentrated hydrochloric acid, reverse extraction equilibrium time is long, high acidity of back washing liquid. Generally by acidic phosphonic type extracting agent made rough erbium, made by electrolysis of molten chlorinated erbium fine erbium. Solvent extraction for centrifugal extraction machine extraction equipment, for example, its for two phase mixture in centrifugal field, to join the extraction solvent, make the purpose of the liquid layer separation. Due to its two phase solution short contact time, high extraction efficiency, equipment maintenance rate is significantly reduced, now has been widely used in the industries of traditional Chinese medicine extraction








DE source extraction recommend the centrifugal extraction machine, extraction of rare earth elements erbium help you understand the extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
