Product Code : EM-Pr-5N-Cu
Praseodymium is a metal element with an atomic number of 59, which is a rare earth metal. The corrosion resistance of praseodymium in the air is stronger than that of lanthanum, cerium, neodymium and europium. One of the uses of praseodymium is for the catalytic cracking of petroleum. Its neodymium praseodymium form enrichment is added to Y-type zeolite molecular sieve to prepare petroleum cracking catalyst, which can improve the activity, selectivity and stability of the catalyst.
