One material used for anodic material of nickel–metal hydride batteries is La(Ni 3.6 Mn 0.4 Al 0.3 Co 0.7). Due to high cost to extract the other lanthanides, a mischmetal with more than 50% of lanthanum is used instead of pure lanthanum. The compound is an intermetallic component of the AB 5 type.
Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties, but have ...
LaNi 5 is a hexagonal intermetallic compound composed of rare earth element lanthanum and transition metal nickel. It presents a calcium pentacopper (CaCu 5) crystal structure. It is a melting compound with the same composition and has hydrogen storage capacity. [3]
Lanthanum forms several alloys with nickel, including LaNi 5, La 2 Ni 7, LaNi 2, ... data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Overlay: lanthanum/strontium (blue), manganese (purple), oxygen (red). 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.
Lanthanum carbonate, La 2 (C O 3) 3, is the salt formed by lanthanum(III) cations and carbonate anions. It is an ore of lanthanum metal ( bastnäsite ), along with monazite . Chemistry
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 ...
A modern ferrocerium firesteel product is composed of an alloy of rare-earth metals called mischmetal, containing approximately 20.8% iron, 41.8% cerium, about 4.4% each of praseodymium, neodymium, and magnesium, plus 24.2% lanthanum. [5] A variety of other components are added to modify the spark and processing characteristics. [2]
