\r\nCrisol de al\u00famina de alta pureza (Al2O3)<\/p>\r\n

Introducci\u00f3n al crisol cer\u00e1mico de al\u00famina de alta pureza<\/strong>
\r\n<\/strong>La pureza del material de al\u00famina de alta pureza suele oscilar entre el 95 % y el 99,7 %. Los crisoles de al\u00famina se utilizan ampliamente en la producci\u00f3n industrial y en entornos de laboratorio. Se encuentran entre los crisoles cer\u00e1micos m\u00e1s utilizados debido a su tecnolog\u00eda avanzada, propiedades bien equilibradas y un coste relativamente econ\u00f3mico. Son adecuados para su uso en hornos de inducci\u00f3n de media y alta frecuencia, hornos el\u00e9ctricos y hornos de vac\u00edo, donde sirven como recipientes de calentamiento.
\r\nEn la metalurgia de alta gama, los crisoles de al\u00famina se utilizan a menudo como revestimientos. Para lograr una mayor pureza en los metales fundidos y evitar la contaminaci\u00f3n causada por el contacto directo con la al\u00famina, se requiere al\u00famina de alta pureza para la fabricaci\u00f3n de crisoles. En algunos casos, es necesaria la pulverizaci\u00f3n de plasma adicional. Por ejemplo, al fundir aleaciones de titanio, se aplica un recubrimiento de Y\u2082O\u2083 a la superficie interior del crisol.
\r\nUno de los principales inconvenientes de los crisoles cer\u00e1micos es su resistencia relativamente baja al choque t\u00e9rmico, lo que limita su vida \u00fatil y el n\u00famero de usos.<\/p>\r\n<\/div>\r\n
