Cer\u00e1mica de nitruro de boro<\/strong><\/h1>\n

El nitruro de boro es un material sint\u00e9tico avanzado material cer\u00e1mico <\/a>disponible en forma de polvo, s\u00f3lido, l\u00edquido y aerosol. Sus propiedades \u00fanicas \u2014desde su elevada capacidad t\u00e9rmica y su extraordinaria conductividad t\u00e9rmica hasta su f\u00e1cil mecanizabilidad y su resistencia diel\u00e9ctrica superior\u2014 convierten al nitruro de boro en un material verdaderamente excepcional.<\/strong><\/p>\n

En su forma s\u00f3lida, el nitruro de boro se conoce a menudo como \u2018grafito blanco\u2019, ya que presenta una microestructura muy similar a la del grafito. Sin embargo, a diferencia del grafito, el nitruro de boro es un excelente aislante el\u00e9ctrico y no necesita humedad para actuar como lubricante. Ofrece una conductividad t\u00e9rmica muy elevada y una buena resistencia al choque t\u00e9rmico, y puede mecanizarse f\u00e1cilmente con tolerancias ajustadas en pr\u00e1cticamente cualquier forma. Tras el mecanizado, est\u00e1 listo para su uso sin necesidad de tratamientos t\u00e9rmicos ni operaciones de cocci\u00f3n adicionales.<\/strong><\/p>\n

En atm\u00f3sferas inertes y reductoras, Nitruro de boro<\/a> Resiste temperaturas superiores a los 2.000 \u00b0C y, en atm\u00f3sferas oxidantes, hasta los 750 \u00b0C. No se ve afectado por la mayor\u00eda de los metales fundidos ni por las escorias, por lo que puede utilizarse como recipiente para la mayor\u00eda de los metales fundidos, incluidos el aluminio, la criolita, el sodio, el hierro, el acero, el silicio, el boro, el esta\u00f1o, el germanio y el cobre.<\/strong><\/p>\n

El nitruro de boro est\u00e1 disponible en diversos grados \u2014A, AX05, HP, M, M26 y ZSBN\u2014 en forma s\u00f3lida y en polvo. Aunque cada grado presenta grandes diferencias en cuanto a la temperatura de funcionamiento, todos ofrecen una serie de propiedades comunes \u00fanicas\u2026<\/strong><\/p>\n
