Lanthanum oxide is a chemical substance, molecular formula is La2O3. Slightly soluble in water, soluble in acid, the dew air easy to absorb carbon dioxide and water, mainly used in the manufacture of precision optical glass, optical fiber.
Slightly soluble in water, soluble in acids and generate the corresponding salts. Air is easy to absorb carbon dioxide and water, gradually became lanthanum carbonate. Calcination of lanthanum oxide and hydration to emit a large amount of heat.
Lanthanum oxide is mainly used in the manufacture of precision optical glass, optical fiber. Also used in the electronics industry for ceramic capacitor, piezoelectric ceramic with agent. Also used as the material of lanthanum system boride, separation of oil refining catalysts.
