Lanthanum Oxide (La2O3)

Lanthanum(III) oxide is La2O3, It is an odorless, white solid substance, insoluble in water, but soluble in dilute acid.

La2O3 is hygroscopic. Under atmosphere, lanthanum oxide absorbs moisture over time and converts to lanthanum hydroxide.

We produce Lanthanum Oxide in high purity 99,99%, 99,999% and Nanoparticles ( Nano powder ) for various applications.
