CAS 7440-10-0: Praseodimio
Descripción:
Praseodimio es un elemento químico con el símbolo Pr y el número atómico 59, que pertenece a la serie de los lantánidos de la tabla periódica. Es un metal blanco plateado que es relativamente blando y maleable, exhibiendo un brillo brillante cuando se corta recién. Praseodimio es conocido por sus propiedades únicas, incluida su capacidad para formar una variedad de estados de oxidación, principalmente +3 y +4, que contribuyen a su diverso comportamiento químico. Es moderadamente reactivo, se empaña en el aire y reacciona con el agua para formar hidróxido de Praseodimio. Este elemento se utiliza principalmente en la producción de imanes permanentes fuertes, así como en varias aleaciones y cerámicas, particularmente en las industrias del vidrio y la cerámica donde imparte un color amarillo. Además, los compuestos de Praseodimio se utilizan en la producción de ciertos tipos de láseres y como catalizadores en varias reacciones químicas. Debido a su abundancia relativamente baja en la corteza terrestre, Praseodimio se extrae típicamente de minerales como la bastnasita y la monacita.

CAS:Praseodymium is a soft, silvery-white metal that belongs to the rare earth metals. It has a high resistance to heat, and does not corrode easily. Praseodymium is used in the production of glass and ceramics, as well as in catalysts for chemical reactions. It can be found in the form of praseodymium oxide or praseodymium chloride and reacts with hydrogen to form a reddish-brown compound. Praseodymium also emits light when heated, which is due to an intramolecular hydrogen reaction. This property can be used for analytical purposes by spectroscopic analysis or by using lasers. Praseodymium has coordination geometry of square planar with four ligands in one plane (Nd(OH)4).
