Lanthanum oxide is a chemical substance, and its Molecular formula is La2O3. Slightly soluble in water, easily soluble in acid, easy to absorb carbon dioxide and water when exposed to air, mainly used for manufacturing precision optical glass and Optical fiber.
Its chemical properties are slightly soluble in water and easily soluble in acids, resulting in the formation of corresponding salts. Exposed in the air, it is easy to absorb carbon dioxide and water, and gradually becomes Lanthanum carbonate. The burned Lanthanum oxide combines with water to release a lot of heat.

Storage precautions: Usually, products are added with polymerization inhibitors. Store in a cool and ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse should not exceed 30 ℃. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants, acids, alkalis, etc. and should not be mixed for storage. Using explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency response equipment for leaks and suitable storage materials.

Lanthanum oxide is mainly used to manufacture precision optical glass and optical fiber. It is also used in electronic industry as ceramic capacitor and piezoelectric ceramic admixture. It is also used as raw material for preparing lanthanum borate and catalyst for petroleum separation and refining
