PRASEODYMIUM CAS 7440-10-0

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is PRASEODYMIUMwhich has developed particularly rapidly in recent years. Do you know about PRASEODYMIUM?

The official answer: Praseodymium is a metallic element with atomic number 59 and is a rare earth metal. The element name is derived from the Greek word for “green”. The crystal structure is a hexagonal unit cell. Praseodymium is more resistant to corrosion in air than lanthanum, cerium, neodymium and rhenium, but exposure to air produces a fragile layer of green oxides, which pure praseodymium must be preserved in mineral oil or sealed plastic. One of the uses of praseodymium is for petroleum catalytic cracking. Petroleum cracking catalysts were prepared in the form of praseodymium neodymium enrichment by adding Y-type zeolite molecular sieves to improve the activity, selectivity and stability of the catalysts. Praseodymium, like other rare earth elements, is lowly toxic and is not a necessary element.
