Lanthanum oxide is used as a catalyst in organic chemical productions, autompbile exhausts, and in improving propellant burning rates. In electronics it can be used in light converting films due to its high photoelectric conversion efficiency. It can also be used in piezoelectric materials, electrode materials, laser materials, hydrogen storage materials, and light emmitting materials. Lanthanum oxide can also be used for manufacturing all kinds of alloy materials, optical glass, and high refraction optical fibers.
