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 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]
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
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]
The price for a (metric) ton [1000 kg] of Lanthanum oxide 99% (FOB China in USD/Mt) is given by the Institute of Rare Earths Elements and Strategic Metals (IREESM) as below $2,000 for most of the period from early 2001 to September 2010 (at $10,000 in the short term in 2008); it rose steeply to $140,000 in mid-2011 and fell back just as rapidly ...
Walmart is known not for making rash, sudden, bold moves. Rather, its MO is to deliberate on big changes it makes, a strategy that has generally paid off over time for the largest U.S. retailer.
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.
Enter the Canon Pixma MG2522 all-in-one, currently on sale at Walmart for just $29. You'd be hard-pressed to buy a single ink cartridge for $29, let alone an entire printer.
