Process Flow Diagram


The applications of praseodymium oxide include:

1. Used in building ceramics and daily-use ceramics, it is mixed with ceramic glaze to make color glaze, and also can be used as underglaze pigment alone.

2. Used in the manufacture of permanent magnets, its anti-oxidation performance and mechanical properties significantly improved, can be processed into a variety of shapes of magnets.

3. Used in petroleum catalytic cracking, adding praseodymium-neodymium enriched material into Y-type zeolite molecular sieve to prepare petroleum cracking catalyst, which can improve the activity and stability of the catalyst.



In sealed double polyethylene bags. The bags are packed in steel drums containing 25 or 50 Kgs net each.
