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.
Lanthanum oxide is also used as a grain-growth additive during the liquid-phase sintering of silicon nitride and zirconium diboride. [ 65 ] Small amounts of lanthanum added to steel improves its malleability , resistance to impact, and ductility , whereas addition of lanthanum to molybdenum decreases its hardness and sensitivity to temperature ...
Lithium lanthanum zirconium oxide (LLZO, Li 7 La 3 Zr 2 O 12) or lithium lanthanum zirconate is a lithium-stuffed garnet material that is under investigation for its use in solid-state electrolytes in lithium-based battery technologies.
Sigma Advanced Genetic Engineering (SAGE) Labs is a division within Sigma-Aldrich that specializes in genetic manipulation of in vivo systems for special research and development applications. It was formed in 2008 to investigate zinc finger nuclease technology and its application for disease research models.
Lanthanum(III) nitrate is any inorganic compound with the chemical formula La(NO 3) 3 ·xH 2 O. It is used in the extraction and purification of lanthanum from its ores. [5] The compound decomposes at 499°C to lanthanum oxide, nitric oxide and oxygen. [3]
Lanthanum(III) sulfide can be prepared from the effect of sulfur vapor on metallic lanthanum: 2 La + 3 S → La 2 S 3. It can also be prepared from the effect of hydrogen sulfide on lanthanum: 2 La + 3H 2 S → La 2 S 3 + 3 H 2. The effect of hydrogen sulfide on lanthanum oxide in the presence of reducing agents also produces lanthanum(III ...
Lanthanum oxalate is an inorganic compound, a salt of lanthanum metal and oxalic acid with the chemical formula La 2 (C 2 O 4) 3. [1] [2] Synthesis.
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.
