  2. Lanthanum - Wikipedia

    en.wikipedia.org/wiki/Lanthanum

    Lanthanum is traditionally counted among the rare earth elements. Like most other rare earth elements, its usual oxidation state is +3, although some compounds are known with an oxidation state of +2. Lanthanum has no biological role in humans but is used by some bacteria.

  3. Lanthanum oxide - Wikipedia

    en.wikipedia.org/wiki/Lanthanum_oxide

    Lanthanum(III) oxide, also known as lanthana, chemical formula La 2 O 3, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is used in some ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts, among other uses.

  4. Lanthanum manganite - Wikipedia

    en.wikipedia.org/wiki/Lanthanum_manganite

    Lanthanum manganite is an inorganic compound with the formula LaMnO 3, often abbreviated as LMO. Lanthanum manganite is formed in the perovskite structure, consisting of oxygen octahedra with a central Mn atom. The cubic perovskite structure is distorted into an orthorhombic structure by a strong Jahn–Teller distortion of the oxygen octahedra ...

    en.wikipedia.org/wiki/Lanthanum_strontium_manganite

    Lanthanum strontium manganite (LSM or LSMO) is an oxide ceramic material with the general formula La 1−x Sr x MnO 3, where x describes the doping level. It has a perovskite -based crystal structure, which has the general form ABO 3 .

  9. Lanthanide - Wikipedia

    en.wikipedia.org/wiki/Lanthanide

    The oxidation states are also very stable; with the exceptions of SmI 2 [27] and cerium(IV) salts, [28] lanthanides are not used for redox chemistry. 4f electrons have a high probability of being found close to the nucleus and are thus strongly affected as the nuclear charge increases across the series; this results in a corresponding decrease ...
