What is Lanthanum oxide CAS 1312-81-8?
Lanthanum oxide is the oxide of lanthanum (III). At room temperature, it is a white powder with a relative density of 6.51 (15/4°C), a melting point of 2307°C, and a boiling point of 4200°C. It is insoluble in cold water and turns into lanthanum hydroxide in hot water. It dissolves in dilute inorganic acids to form lanthanum salts of the corresponding acids, and is insoluble in Chemicalbook acetone. When melted with sodium hydroxide, it forms sodium tetravalent lanthanum acid. It is formed by absorbing carbon dioxide from the air to become lanthanum carbonate. It is produced by calcining lanthanum oxalate, lanthanum nitrate, lanthanum carbonate, or lanthanum hydroxide. It is used as an analytical reagent and refractory material; it is used in the manufacture of optical glass, industrial ceramics, gas lamp shades, special alloys, etc.
