Description & Features

Descriptive: WNX employs advanced automated production technology and uses high-quality raw materials to produce high-quality Lanthanum Oxide.

Key Features:

High Purity:Lanthanum Oxide contains no impurities from rare earth elements (such as iron, calcium, sodium), and the impurity content is low.

Good Solubility: Lanthanum Oxide can dissolve rapidly in water and strong acids.

Consistency: The strict batch management in the production of Lanthanum Oxide ensures stable quality for industrial large-scale production.

Optical glass and ceramics: Lanthanum oxide is the core raw material for manufacturing precision optical glass and optical fibers, significantly enhancing the refractive index and dispersion properties of the glass. It is widely used in the production of advanced optical lenses for cameras and microscopes. In the field of electronic ceramics, it is used as an additive to manufacture ceramic capacitors and piezoelectric ceramics to improve the electrical properties and temperature stability of the materials.

Catalyst: In the petrochemical industry, lanthanum oxide is used as an important component of catalytic cracking (FCC) catalysts, which helps increase the output and quality of gasoline. It can also serve as a catalyst for specific chemical reactions, such as the oxidation of carbon monoxide and the reaction of methane oxidation to form ethane and ethylene.

Functional materials: Lanthanum oxide is the raw material for preparing lanthanum boride (LaB₆), which is an excellent thermoelectronic emission cathode material. Lanthanum oxide also has important applications in fields such as hydrogen storage materials and fuel cells. For example, lanthanum-nickel alloys can be used for hydrogen storage.
