Main Uses:

 

Used in architectural ceramics and domestic ceramics, it is mixed with ceramic glaze to make a color glaze, but also can be used as a separate underglaze pigment, the pigment made of light yellow, pure and elegant color; Used to make permanent magnets. The use of cheap praseodymium neodymium metal instead of pure neodymium metal to manufacture permanent magnet materials, its antioxidant properties and mechanical properties are significantly improved, can be processed into various shapes of magnets. Widely used in all kinds of electronic devices and motors; For catalytic cracking of petroleum. The activity, selectivity and stability of petroleum cracking catalyst can be improved by adding the preconcentration of praseodymium and neodymium to Y zeolite molecular sieve. For abrasive polishing; It is also used in the field of optical fiber.

1. As a catalyst: Praseodymium (III) oxide shows good catalytic activity in many catalytic reactions.

2. As a colorant: Praseodymium oxide (III) has good coloring characteristics and is widely used in the coloring process of enamel and glass products.

3. As an optical material: praseodymium (III) oxide can be used to prepare special optical glass, which has the characteristics of adjusting optical properties, and is often used in the manufacture of optical instruments and displays.
