Paladio y Platino: acerca de los elementos<\/h2>\n

Paladio<\/span><\/span><\/h3>\n

El paladio, platino, rodio, rutenio, iridio y osmio forman un grupo de elementos denominados metales del grupo del platino (PGM). Estos tienen propiedades qu\u00edmicas similares, pero el paladio tiene el punto de fusi\u00f3n m\u00e1s bajo y es el menos denso de ellos. M\u00e1s de la mitad del suministro de paladio y su cong\u00e9nere, el platino, se utiliza en convertidores catal\u00edticos.<\/span><\/span><\/span><\/span><\/p>\n

Platino<\/span><\/span><\/h3>\n

El platino es un metal de transici\u00f3n denso, maleable, d\u00factil, muy poco reactivo, precioso, de color blanco plateado. El platino es uno de los metales menos reactivos. Tiene una notable resistencia a la corrosi\u00f3n, incluso a altas temperaturas, por lo que se considera un metal noble. El platino se utiliza en convertidores catal\u00edticos, equipos de laboratorio, contactos y electrodos el\u00e9ctricos, term\u00f3metros de resistencia de platino, equipos de odontolog\u00eda y joyer\u00eda.<\/span><\/span><\/span><\/span><\/span><\/p>\n

Paladio<\/span><\/span><\/a><\/h3>\n

M\u00e1s de la mitad del suministro de paladio y su cong\u00e9nere, el platino, se utiliza en convertidores catal\u00edticos, que hace hasta el 90% de los gases nocivos del escape de los autom\u00f3viles en sustancias menos nocivas. El paladio tambi\u00e9n se utiliza en electr\u00f3nica, odontolog\u00eda, medicina, purificaci\u00f3n de hidr\u00f3geno, aplicaciones qu\u00edmicas, tratamiento de aguas subterr\u00e1neas y joyer\u00eda. Las aleaciones a base de paladio se utilizan ampliamente en aplicaciones de tecnolog\u00eda de pilas de combustible. El metal tambi\u00e9n se emplea en procesos hist\u00f3ricos de impresi\u00f3n fotogr\u00e1fica. El paladio se ha utilizado como metal precioso en joyer\u00eda desde 1939 como alternativa al platino en las aleaciones denominadas \u201coro blanco\u201d.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Platino<\/span><\/span><\/a><\/h3>\n

El platino es principalmente un metal industrial. Es un material cr\u00edtico para muchas industrias y se considera un metal estrat\u00e9gico. El platino se utiliza como catalizador, el platino se encuentra principalmente en convertidores catal\u00edticos de veh\u00edculos que reducen los productos qu\u00edmicos t\u00f3xicos de escape y tambi\u00e9n en las pilas de combustible para aumentar la eficiencia. El uso m\u00e1s com\u00fan del platino es como catalizador en reacciones qu\u00edmicas, a menudo como negro de platino. En los convertidores catal\u00edticos, el platino permite la combusti\u00f3n completa de bajas concentraciones de hidrocarburos no quemados del escape en di\u00f3xido de carbono y vapor de agua. El platino se ha utilizado en dispositivos de termopar que miden la temperatura con alta precisi\u00f3n.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n
