Item details

Lanthanum oxide is La2O3, an inorganic compound containing the rare earth element lanthanum and oxygen. It is used to develop ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts.

La2O3 has a band gap at approximately 5.8 eV.[1] It has the lowest lattice energy, with very high dielectric constant, ε = 27. La2O3 is widely used in industry as well as in the research laboratory. Lanthanum oxide is an odorless, white solid that is insoluble in water, but soluble in dilute acid. Depending on the pH of the compound, different crystal structures can be obtained.[citation needed] La2O3 is hygroscopic; under atmosphere, lanthanum oxide absorbs moisture over time and converts to lanthanum hydroxide. Lanthanum oxide has p-type semiconducting properties. Its resistivity decreases with an increase in temperature. Its average room temperature resistivity is 10 kΩ·cm.

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 Also for clarity the Free shipping is no longer applicable on exchanged items.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
