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.
Calcination of lanthanum(III) sulfate in oxygen current at 750 °C: [4] La 2 (SO 4) 3 + O 2 → La 2 O 3 ·SO 3 + 2SO 3. The resulting product is reduced with hydrogen when heated: La 2 O 3 ·SO 3 + 4H 2 → La 2 O 2 S + 4H 2 O
Holmium(III) oxide, or holmium oxide is a chemical compound of the rare-earth element holmium and oxygen with the formula Ho 2 O 3. Together with dysprosium(III) oxide (Dy 2 O 3), holmium oxide is one of the most powerfully paramagnetic substances known. The oxide, also called holmia, occurs as a component of the related erbium oxide mineral ...
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]
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.
Lanthanum aluminate is an inorganic compound with the formula LaAlO 3, often abbreviated as LAO. It is an optically transparent ceramic oxide with a distorted perovskite structure . Properties
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.
