Molecular formula: La2O3;
Molecular weight: 325.81;
Density 6.51g/cm3;
Melting point 2217 ° C;
Boiling point 4200 ° C;
Slightly soluble in water, soluble in
acid to form the corresponding salts. It is easy to absorb carbon dioxide and
water in the exposed air and gradually becomes lanthanum carbonate. The burning
of lanthanum oxide combines with water to release a large amount of heat.

use:
1. Nano lanthanum oxide is applied to
piezoelectric materials to increase the piezoelectric coefficient of the
product and improve the electrical energy conversion rate of the product.
2. Nano lanthanum oxide is used to
manufacture precision optical glass, high refractive optical fiber board and
various alloy materials;
3. Nano lanthanum oxide is used to
prepare catalysts for organic chemical products and to neutralize automobile
exhaust catalysts; nano lanthanum oxide can effectively catalyze the thermal
decomposition of absorbents and potentially improve the burning rate of
propellants, which is a promising catalyst. .
4. Nano lanthanum oxide is applied to
light-converting agricultural film, and the photoelectric conversion efficiency
of nano lanthanum oxide is high, and the weak light source is effectively
utilized to save energy loss.
5. Nano lanthanum oxide is applied to
electroforming electrode material, adding 0.2%-0.5% nano lanthanum oxide can
effectively improve the electro-erosion resistance of electroformed electrode
materials and reduce electrode loss;
6. Nano lanthanum oxide is applied to
luminescent materials (blue powder), hydrogen storage materials, and laser
materials;
