\r\nCadinho de Alumina de Alta Pureza (Al2O3)<\/p>\r\n

Introdu\u00e7\u00e3o ao cadinho cer\u00e2mico de alumina de alta pureza<\/strong>
\r\n<\/strong>A pureza da alumina de alta pureza varia tipicamente de 95% a 99,7%. Cadinhos de alumina s\u00e3o amplamente utilizados na produ\u00e7\u00e3o industrial e em ambientes laboratoriais. Eles est\u00e3o entre os cadinhos cer\u00e2micos mais utilizados devido \u00e0 sua tecnologia avan\u00e7ada, propriedades balanceadas e custo relativamente baixo. Cadinhos de alumina s\u00e3o adequados para uso em fornos de indu\u00e7\u00e3o de m\u00e9dia e alta frequ\u00eancia, fornos el\u00e9tricos e fornos a v\u00e1cuo, onde atuam como recipientes de aquecimento.
\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\nUma das principais desvantagens dos cadinhos de cer\u00e2mica \u00e9 sua resist\u00eancia relativamente baixa ao choque t\u00e9rmico, o que limita sua vida \u00fatil e o n\u00famero de usos.<\/p>\r\n<\/div>\r\n
