Applications
Lanthanum oxide has a wide range of applications, mainly including:
1. Manufacture of special alloy precision optical glass, high refractive optical fiber plate.
2. Used as a catalyst for a variety of reactions, such as doping cadmium oxide when catalyzing the oxidation reaction of carbon monoxide.
3. Lanthanum oxide infiltrated with lithium oxide or zirconium oxide can be used to manufacture ferrite magnets.
4. Manufacture of ceramic capacitors, piezoelectric ceramic dopant and X-ray luminescent materials such as lanthanum bromide powder.
In addition, lanthanum oxide can also be used in the manufacture of electronic components, glass and ceramic products. In short, lanthanum oxide has a wide range of applications in many fields.
