Lanthanum Oxide La2O3 CAS 1312-81-8
Slightly soluble in water, easily soluble in acid and the formation of corresponding salts. Exposed air is easy to absorb carbon dioxide and water, and gradually become lanthanum carbonate. The burning lanthanum oxide combines with water to release a great deal of heat.
Mainly used for manufacturing precision optical glass and optical fiber. Also used in electronic industry for ceramic capacitors, piezoelectric ceramic additives.
Also used as raw materials for lanthanum boride, oil separation refining catalyst.
1) Wear suitable protective clothing.
2) In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
