Item details

ERBIUM OXIDE:Erbium(III) oxide, is synthesized from the transition metal erbium. It was partially isolated by Carl Gustaf Mosander in 1843, and first obtained in pure form in 1905 by Georges Urbain and Charles James.[2] It has a pink color with a cubic crystal structure. Under certain conditions erbium oxide can also have a hexagonal form.[3] Erbium oxide is toxic when inhaled, taken orally, or injected into the blood stream in massive amounts. The effect of erbium oxides in low concentrations on humans over long periods of time has not been determined. However, this compound should be handled with care.[4]

Uses Include:The applications of Er2O3 are varied due to their electrical, optical and photoluminescence properties. Nanoscale materials doped with Er+3 are of much interest because they have special particle-size-dependent optical and electrical properties.[8] Erbium oxide doped nanoparticle materials can be dispersed in glass or plastic for display purposes, such as display monitors. The spectroscopy of Er+3 electronic transitions in host crystals lattices of nanoparticles combined with ultrasonically formed geometries in aqueous solution of carbon nanotubes is of great interest for synthesis of photoluminescence nanoparticles in ‘green’ chemistry.[7] Erbium oxide is among the most important rare earth metals used in biomedicine.[9] The photoluminescence property of erbium oxide nanoparticles on carbon nanotubes makes them useful in biomedical applications. For example, erbium oxide nanoparticles can be surface modified for distribution into aqueous and non-aqueous media for bioimaging.[8] Erbium oxides are also used as gate dielectrics in semi conductor devices since it has a high dielectric constant (10-14) and a large band gap. Erbium is sometimes used as a coloring for glasses[10] and erbium oxide can also be used as a burnable neutron poison for nuclear fuel.

Returns & exchanges

I can not offer returns, refunds or exchanges on chemical materials due to the fact that there is no guarantee that the material has not been tampered with and I can not resell it to someone else with confidence that I have the same materials that was originally purchased from my supplier. Therefore I repeat there are NO returns on chemical materials.

I offer exchanges only on Ceramic art for equal or greater value item. The buyer is required to pay to return the original item shipping and the new item shipping as well as 25% restocking fee. Also for clarity the Free shipping is no longer applicable on exchanged items. The new item will be shipped when the original item is received intact and the additional fees have been paid.
No item will be exchanged of a lesser value item with the buyer expecting refund.

Paintings are not returnable
