1. Ceramic industry: Praseodymium oxide is an important raw material for ceramic glazes, used to manufacture brightly colored and stable ceramic products, especially yellow ceramic pigments.
2. Glass industry: Praseodymium oxide, as a coloring agent, has important applications in the glass industry. Especially when used in combination with other rare earth elements, green glass can be made for imitating gemstones or other decorative items.
3. Rare earth permanent magnet alloys: Praseodymium oxide is one of the raw materials for manufacturing rare earth permanent magnet alloys, which have wide applications in electronic devices, motors, and other fields.
4. Petroleum catalytic cracking: Adding praseodymium neodymium enrichment to Y-shaped zeolite molecular sieve to prepare petroleum cracking catalysts can improve the activity, selectivity, and stability of the catalyst, which is of great significance in the petroleum industry.
5. Other applications: Praseodymium oxide can also be used as a fluorescent powder additive, a raw material for the preparation of refractory ceramics, a doping material for optical fibers, and electronic ceramics.
