Lnthanum 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. 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. 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.
