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

Iridio<\/span><\/span><\/h3>\n

El iridio es un metal de transici\u00f3n muy duro, quebradizo, de color blanco plateado del grupo del platino, generalmente se le atribuye al iridio el segundo elemento m\u00e1s denso (despu\u00e9s del osmio). Tambi\u00e9n es el metal m\u00e1s resistente a la corrosi\u00f3n, incluso a temperaturas de hasta 2000 \u00b0 C.<\/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

Iridio y Platino – Aplicaciones<\/h2>\n

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

El iridio es consumido principalmente por las industrias automotriz, electr\u00f3nica y qu\u00edmica. El iridio met\u00e1lico se emplea cuando se necesita una alta resistencia a la corrosi\u00f3n a altas temperaturas, como en las buj\u00edas de alto rendimiento, crisoles para recristalizaci\u00f3n de semiconductores a altas temperaturas y electrodos para la producci\u00f3n de cloro en el proceso cloro-\u00e1lcali. La demanda de iridio aument\u00f3 de 2,5 toneladas en 2009 a 10,4 toneladas en 2010, principalmente debido a las aplicaciones relacionadas con la electr\u00f3nica que aumentaron de 0,2 a 6 toneladas; los crisoles de iridio se utilizan para cultivar grandes monocristales de alta calidad, cuya demanda ha aumentado considerablemente.<\/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
