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 ...
LSAT is the most common name for the inorganic compound lanthanum aluminate - strontium aluminium tantalate, which has the chemical formula (LaAlO 3) 0.3 (Sr 2 TaAlO 6) 0.7 or its less common alternative: (La 0.18 Sr 0.82)(Al 0.59 Ta 0.41)O 3. LSAT is a hard, optically transparent oxide of the elements lanthanum, aluminium, strontium and tantalum.
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 barium copper oxide, or LBCO, is an inorganic compound with the formula CuBa 0.15 La 1.85 O 4. It is a black solid produced by heating an intimate mixture of barium oxide, copper(II) oxide, and lanthanum oxide in the presence of oxygen. The material was discovered in 1986 and was the first high temperature superconductor. [1]
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 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.
Europium(II) oxide can be obtained by the reduction of europium(III) oxide with metallic europium at high temperatures. It has a rock-salt structure, is a deep red solid, and is ferromagnetic at 77 K. It has the potential to become a magnetic refrigeration material (ΔS mag =−143 mg/cm 3 K，50 kOe).
