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]
